Hello,
I am very interested in your keyglove project. It looks like it will turn out very nice.
Here's a thought on the conductive fabric:
Instead of trying to solder the wires to the fabric, what if you did this...
If you got some stranded wire, and the strands were very fine. Almost like the type that they use in the wires on earbuds. Anyway, the strands are very fine.
Then you fan out the the strands, and lay the piece of conductive fabric over that. Then you sew the fabric to the glove, with the strands of wire sandwiched between the glove and the fabric. Also, I've never used it, but I picture using conductive thread to sew it together.
I hope that is pretty easy to visualize, I will try and get some pictures up later of what I mean.
