It is finished, yay! It's about 64" (160cm) long, 7/8" (22mm) wide. If I'd really worked at it, I might have been able to eke out another inch or so, but that's OK.
I ended up doing 17 motifs total. I started and ended with a little diamond, and then alternated swirl/S/leaf motifs with motifs that were blockier and more diamond-based. I probably could have skipped the last diamond motif, but I was having fun, plus I didn't know how much more plain twill weaving I'd be doing to finish the band.
The motifs are all by Claudia Wollny, from Tablets at Work, Lily Grove, and Lily Grove 2. The first swirl motif (second motif overall) is in the errata so of course I used that version of the chart. The other charts were fine as printed.
There are some areas that look messier, where some motifs are a bit elongated compared to others. I'm not totally sure why that happened.
Is it because these are areas where I was more likely to mess up and thus unweave/reweave? Is it because these areas are after I've advanced the warp, untangled stuff, and re-tensioned everything, and thus there were slight differences in tension from thread to thread? Did I relax or tense up? Did the cotton stretch out differently? Was I closer/farther from the cards and this affected things somehow? Will it relax out now that the band is no longer under tension? Is it an illusion, based on the motifs' different widths and lengths?
I am not sure, but it's something I'll pay attention to in the future. I'm hoping it's one of those things that will straighten itself out through practice and experience.
I'm also not sure how much more square I want to try to make the motifs. If I beat too hard then the band will be too stiff rather than flexible (yeah, get your mind out of the gutter). I do loosen up a bit on weft tension since weft tension does interact with how close the picks are to affect the various angles and thus elongation of the motifs. If that makes sense. Also, if the weft tension is a little looser, I believe I can achieve closer-together picks and beat the weft down a little tighter.
I do like the natural elongation of the swirly motifs. It's quite possible that this may well be a feature of the technique, similar to how it is in double-face. Which makes some sense since 3/1 twill is so closely related to double-face. Or maybe it's because I mostly use cotton. Or I like a more flexible band thus don't weave too tightly.
-----------------
Here's the list of the motifs I used:
Little diamond separator motif (every odd motif from first to seventeenth): Lily Grove, p.130, V-1
First swirl (second motif): Tablets at Work, p.271 (from the errata)
First diamond (fourth motif): Tablets at Work, p.271, upper right
Second swirl (sixth motif): Lily Grove, p.28, II-7
Second diamond (eighth motif): Lily Grove, p.141, V-27
Third swirl (tenth motif): Lily Grove 2, p.44 II-12
Third diamond (twelfth motif): Tablets at Work, p.275, upper right
Fourth swirl (fourteenth motif): Tablets at Work, p.285, lower right
Fourth diamond (sixteenth motif): Lily Grove 2, p.221, V-4
I love all of these motifs and would be happy to use them again. Some of the swirl/leaf motifs have repetition lines in case I want to make a much longer leafy tendril, for example. Which I might! There are many other motifs I'd like to play with. It is very nice of Claudia Wollny to have provided such a rich set of charts, and to have made all of them quite modular so they can be plugged in wherever or whenever one wants.

What did I learn?
I like 3/1 twill. I can follow Wollny's charts and string together motifs in a pleasing way. This band was a lot of fun to weave although of course it's slower than some of the other tablet weaving techniques.
The underlying logic of 3/1 twill makes sense, which means that I should try designing a few motifs to refine my understanding.
Un-weaving is tedious but I seem to be able to do it without too much fuss. I'm comfortable doing what I need to do in order to fix my mistakes.
Lacis cards are perfectly reasonable to weave with.
-------------
I'm not sure what I'll be doing next. I'd like to try Collingwood's two-pack method for doing plain 3/1 twill to see if that is faster and/or flows well. Dunno if I'd add motifs or not; I'll have to think about it and maybe do some charting to see what else would need to change in order to have the proper twill background structure.
I have some other ideas about what else I'd like to do in the near future, so I guess I'll see what I'm inspired to do first.
