Tote bags

Recently, I've been taking some free classes on, and enjoying them thoroughly.

Their free classes are short, about an hour or so of video content, broken up into smaller lessons, and once you sign up for a class (free or otherwise), you have access to it forever.

I have learned more about cleaning my sewing machine, troubleshooting when it doesn't work right, using different feet with it, etc.

I also learned how to sew a really cute reversible tote bag, and it's super easy and very well explained! That class, called "Bag-Making Basics: Reversible Tote & Zipper Pouch" also includes a smaller pencil bag with a zipper, but I haven't gotten to that part yet. (Sadly, I cannot seem to link directly to that class, but you can find it on the free classes page linked above) It's a great class for a beginner.

I hope you'll join me in the class and show me your creations too!

3D Orthogonal Draft - less muddy?

I realized my post yesterday was probably pretty unclear, without a draft. Here is my best attempt at a draft:

That does convey more-or-less what I'm doing, in that if you were to thread this up and weave it you should get the same result, but it does not convey well how it actually works on the loom.

In reality, all the purple picks in each of those triangles of purple stack up on top of each other, so I have 7 picks of purple one atop another, as I look down at the fell. Then I change the tabby shed in the black/gray/white threads on 1234. Because they fell is really tall, from all those purple wefts, the black/gray/white threads end up going all the way from top to bottom of this stack of yarns, or vice versa, when I change sheds. A little dot of black or gray or white shows on the top & bottom surfaces, the rest of the thread goes vertically straight down between those surfaces.

What about that weird tie-up?

For a countermarche, this is not a normal tie-up. In order to weave this with one treadle for each weft shot, I would need 14 treadles. But I also want to try weaving twill on shafts 1234, so I wanted to keep some treadles available for that.

Also, in reality I'm weaving shafts 5-10 in order for one "pick", but then 10-5 on the next, so I don't get a big float on the side when the weft goes back to the top.

A skeleton tie-up seemed like a good way to deal with that. With a skeleton tie-up, you can treadle with 2 feet to get more combinations than you have treadles for.

I didn't know if that was possible on a countermarche, so I Googled it, and found a great article by Madelyn Van Der Hoogt on the subject, here is a link to the PDF:

My weaving software doesn't show the bubbles one would normally draw on a countermarche tie-up. If it did, you would see that the 2 treadles for shafts 1-4 are tied up fully, so when 1&3 go down, 2&4 go up, and vice versa. On shafts 5-10, those treadles are tied so that any shaft that isn't going down is going up. So in a sense I've tied up as if I had 2 countermarche looms, one for shafts 1-4, and one for shafts 5-10.

Yes, this means I've effectively avoided doing a proper countermarche tie-up! I'll get to that eventually, I'm sure.

Orthogonal Weaving

A friend loaned me her 12-shaft countermarche loom while she is moving.

My first thought: Lovely!

My second thought: Eek!
I've never tied up a countermarche loom before.

My third thought: Eek!
I couldn't think what to do with 12 shafts. I have up to 8, and I want to make the most of this opportunity.

So, I Googled. First I googled "weaving", and went to Images. There I found several images of handwovens that inspired me. (Who'd have thunk I'd be interested in Crackle? But maybe I'll do that sometime soon.)

Next I Googled "woven", and went to Images. There I found more things that inspired me - but often they were images of things that were not woven. Like quilts, for instance.

But then I found this:
It's the full text of a book about advances in weaving, and about new ways of using weaving in other fields, like architecture.

Then an image in Chapter 5, Multiaxis Three Dimensional (3D) Woven Fabric really got my attention:
The image on the right, a cross-section of a side view of a loom designed to weave the fabric shown in the images above these, was something I could almost understand. My way to achieve better understanding was to set the loom up and weave it.

Here is the result:

This fabric requires 7 weft picks to make 1 "row" of fabric. I was having trouble with the orange/yellow warp yarns not getting caught by the weft, so I used 2 bobbins (one blue, one purple) going in opposite directions in each shed. The orange/yellow warp ends up completely covered.

The black/gray/white warp is actually weaving in the Z-axis. It's doing plain weave, and after 7 shots (between warp layers) in Tabby A, it switches to Tabby B. So it's going up, then down, through the woven structure.

The orange/yellow warp yarns are not weaving around anything. They are straight, and 6 layers deep (threaded on 6 shafts). I'm using the loom to lift each layer so I can put the bobbins through between layers.

The weft yarn is also straight, and not actually weaving around anything (except at the edges when they turn to back through a different shed). The section of toothpick weft conveys that more clearly, I hope.

So, the only yarn that is actually required to be soft and pliable is the black/gray/white yarn. In architecture, this structure could be used with rebar in place of the orange/yellow warp and also in place of the weft, as long as something more pliable (wire?) was used in the Z-axis, the way the black/gray/white warp is here.

Clear as mud?

If there was a way to make all these fibers stick together (i.e. glue, felting, etc.), a loom could weave a solid that then could be machined into shapes. You could weave the 2x4's to build your house with. Except that, even though this fabric is solid, it is pliable. I can twist it. I guess if you wove it with fiberglass and then melted it into a semi-solid blob, it wouldn't flex so much.

So, what's it for? Any ideas? I'm working on a list of thoughts, so far it's things like making a square rope, or decorative ideas. With enough shafts, it would be possible to weave a bag with thick solid sides. Joe suggested a yoga mat, which would probably work well. That made me think of a saddle blanket. I don't think this would be hard-wearing enough for that, though.

If I treat the 6 shafts with orange/yellow as a tripleweave, I could weave a folded fabric like a letter Z, and then stitch the layers together with the black/white, or leave them unstitched so they could unfold. Woven pleats! But if one pleat requires 6 shafts, a fabric with several would be a real shaft hog.

Please share your ideas!

Cute Ring

I made this ring last night, following the instructions I found here:

Which I found as a link from this page:

It was under "Anillos/Rings-2". There are quite a few interesting collections here for jewelry, kumihimo, sewing, etc.

It was surprisingly easy, just required some seed beads and a few small lucite beads. Took a couple of hours, I think. I had never done peyote stitch before, as far as I can recall, but I figured it out from the pictures (the steps in the instructions aren't entirely helpful on that). Once the band itself was made, joining it up into a ring and adding the decorations is very clearly explained in the instructions.

Today I discovered that the peyote stitch was better explained in her other free tutorials here:

From there you can get to her tutorial shop, where she sells tutorials for other lovely things.

Secret Productivity Weapon: Craft Cart

I have been way more productive lately with these small projects like kumihimo, without really feeling like I'm doing that much more. Why? Because I assembled a small rolling workstation, with various tools and materials I use often. At times when all I feel like doing is vegging out in front of the TV, I now can use that time productively, repairing my broken junk jewelry or experimenting with beads or cords.

When not in use, the cart folds up and doubles as an end table in the living room.

I used a nifty old typewriter cart with drop leaves on both sides, which my dad was getting rid of. I added a board for a top (it didn't have a top), a work light, some plastic drawers underneath, and a strip of LED lighting under the top, to better see the contents of the drawers. I also added a couple of magnetic hooks to the backs of the front legs to hold a small pair of scissors on one side, and some other small items on the other side (these aren't visible):

You can see my cat Spots in the foreground, trying to get some attention!

Then I added a power strip to the back, plus a wall pocket to hold my notes, and a matching magnetic bin for holding miscellaneous items too large for the drawers (it's a black mesh thing stuck to the edge of the tabletop). All this stuff is invisible when the cart is pushed against the wall:

I would like to add a glass top, so I can see down into the drawers more easily.

When I'm done using it, I clear everything but the lamp off the top, fold down the sides, and it's just a fun end table. When the LED strip is not on, the drawers underneath are not very noticeable.

Kumihimish Bracelets

I've made several bracelets with this technique. Here are some:

Kumihimish continued: 7-strand braid for guild project

My guild is working on a project involving the 7-strand braid. I've done some experimentation and wanted to share my results, so here is what I've come up with. I think others may have better ideas, this is just to share my drafting method & give a jumping off point for your experimentation:

The drafting notation is given for the first braid on the first page, at top left above. These numbers are clockwise around a braiding disk, assuming slot 8 is empty, and that you are doing a right-hand braid, as explained on kimadagem's Simple Kumihimo page.
Some of the drafts on these 2 pages are repeats, I only sampled the unique ones.

The graph paper I've been using is from Incompetech. They have many graph paper generators, this diamond is just one of them. I set the line color to gray & printed a few sheets to play with.

The 7-strand braid draft is a double-diamond or double-lozenge shape. I just draw in some of those, and number one set, and then fill in colors in the repeat to see what the result will be.

Below is a collection of braids I did with the guild project colors, just seeing what they do together. The yarns are mostly things I picked up at a recent estate sale for a member. She had a marvelous collection of sparkly threads in many colors, so I tried incorporating them. They don't scan well, but you get the idea.

The last braid at the bottom is an 11-strand braid, which is made the same way as the 7-strand braid, except you use a card with 12 slits, and you skip 4 threads, instead of skipping 2 as in the 7-strand braid. I have done several bracelets in the 11-strand braid, with nice results. I'll post some of those next time.
