Dragon Scale for Sewing

I wanted to make a glove with floppy dragon scales that rattle when you move your hand so I printed one scale, and then one more, and before I knew it, I had a hundred of them.

Anyway, it's a fun way to sew (or end up hating sewing) - take the needle from the inside of the cloth through the hole in the scale, then back in the cloth from the outside and then tie a little knot on the underside of the cloth so it stays in place. (not that I'm an expert, but I'm happy to hear if there's a better way to sew them in)
