I haven't an idea in mind, will just have to go with the flow.
I have finished my tapestry. It is much smaller than I had hoped as the larger one was a disaster - with a capital D!!
Now I have a piece that I can put in the exhibition my group has committed to (more on that soon). I haven't cut if off the loom yet, but will do so tomorrow. Then spend the several hours it takes to tidy up the ends, braid the edges, etc. Then I can relax and have another look at the piece that was stressing me.
I have realised that I was rather tense at the time and I think it shows in the tension (tense - tension, get it??). No surprise there. So I may pull out the very tight weaving, that is mostly on the sides, and see if I can make it less pulled in.
If nothing works, I may put it in the compost heap and see what happens, or use it in a machine embroidery piece. It may not work but now it doesn't matter as I have the smaller piece to put in the exhibition. I can play. Or throw it away.
