I made these as a practice exercise to stitch curvy lines. The volunteer position to teach refugee women to sew was the reason behind it. I heard that they are uneasy about sewing on paper. The idea was to have them practice sewing curvy lines on paper because it's easier and also less costly (no destruction of fabric). But, they are not comfortable with sewing on paper. I can sort of understand, because my Eastern European family doesn't always quite get when I sew on paper. I think it's because sewing is supposed to be a practical and useful skill. Making garments, that's productive. While sewing on paper is 'destructive'. There is no purpose. Except in art making.
Anyway.....I though if I have them make greeting cards with crescent moons, which are cutouts from reject black and white paper, will go a bit easier. I haven't introduced the idea to them yet. So we'll see.
