What I did find, though, was a woman who does a lot of sewing. She'd brought along a pile of buttons, but didn't really expect anyone to want them. As you might expect, there were a lot of ordinary buttons, but also a large number of colored and shapes buttons and some large ones. I bought the lot for 10 euros, and both of us were pleased with the bargain.
I also found these little clay faces for 50 cents each. They will be lovely for art dolls. I'm going to try making a mould from them using Fimo, so I can reproduce them using a lighter, air drying (paper) clay.
