I made some children's design pillow cases for a Craft Show and need to know what I should charge. Some are cotton fabrics, a couple are made of pretty flannel, i.e. the typical ones with a 9" top and a 1" strip between the bottom and top. I paid about $8.00 in material for each pair. What I don't sell, I'll donate. What else would be fast for a Craft Show. I signed up months ago and other that two fairly nice quilts, I have nothing ready.
