I have joined my first fabric swap. You purchase 1 metre of fabric and cut it into 5" squares ( a charm pack). You send it to the person who is organizing the group with a self addressed stamped envelope. You then get a charm pack back of mixed fabric with a theme. The theme of this group is fabric with writing on it. Here is the metre that I bought and will be cutting up. I am looking forward to getting my package by the end of March. Fortunately it is a Canadian group. At least I understand the postal system even if it is expensive.
