Bits of natural fiber yarn swap

Lately I've doing lots of projects with yarn small amounts of many colors. So I was wondering, if there are more of us, who have the same problem - having to buy the whole skein just to get bits from it. Swap should help! For this swap you will have to send each partner 15 different colors(well, it can be several different greens, etc.) of yarn at least 10 yards(meters) long. IT HAS TO BE NATURAL FIBER YARN. Cotton, wool, linen, soy, alpaca,etc. You are welcome to create a swap for artificial fibers, if you prefer them. This should be very inexpensive to send, so I make it international. Post in the comments below, what colors you like and dislike, so your partner would try to match the best s(he) can, but understand that it might be not 100 percent possible. You have to have at least 5 rated type 3 swaps, and no recent 3s or 1s.
