Frankly, I cannot remember if I already ordered these samples, but it's OK. I found out today that when ordering from http://www.fashionfabricsclub.com/, you can order in fractions of a yard. For the four I ordered, I only ordered 1/8th of a yard, so the entire order was under ten dollars. That's a great deal.
For reference, I ordered the four fabrics discussed in this blog post.
Today I placed my order. I only write this down in case I forget about it.
