Alright, let's try this with something that's closer to the final shape.

Got the soldering at least a little bit neater this time.

And here's a first run at a character design. I can already see things that need changing, but it's in the ballpark. (And I didn't bother with matching thread, figuring this wouldn't be the final - so you can see my little stitches here.)

Hedgehog-ish.

Looking at the size of this, it seemed like 5 LEDs might be better than 3, so I got those sewed up in a line.

And now let's wrap the felt around the innerds...

Argh. Those LEDs are just not in the right place at all. Bummer. I guess that's why we test these things!
