Here's something that caught my eye while surfing the net
These are bright and colorful and in "larger sizes" but since they don't give any size as a reference, I have no clue. I think the price is in pounds, which is approximately $2 American dollars to each pound. (at least right now it is, who knows when you look at it).
I would think they are made of cotton or rayon motifs and sewn together, with a dyed slip underneath. It must be fingering weight or finer because it looks delicate. Pretty cool stuff - check it out when you get a chance.
