Well, here is the result of my experiment with embroidery floss and a very small crochet hook.
My first ever granny squares, and they are rather tiny!
The black beaded one is about 2cm in diameter, and the bronze one is about 2.5cm or 1".
I actually started the idea with beading wire, but I couldn't get it to bend enough to crochet with. (Has anyone else tried this? And if you did, were you successful?)
Now I need to figure out which way I am going to use them ;)
I have a couple of ideas... any suggestions?
