I have participasted in boomersng snd blovk swaps. I enjoythe varied blocks I have received although I had some that were too small to fit in the quilt. I liked the challenge of making blocks with other people's fabric. I tried new blocks and found it exciting. I did however make a new block that did not make the 12 1/2 inches. I accendently wacked off too much when I squared up the block. I contacted the person through the board and asked for another fat eighthShe sent it to me and I sent back a good block and the short block. You need to be honorable. It is a great place to exchange work. I like making complicated blocks so it is not so boring. Others need to grow into that. I let the fabric and colors speak to me. You will get some blocks you can not use but you will also get some fantastic blocks. It is the nature of the world as it really is. Any experience gains you knowledge and many are willing to help you. It is a great place to learn and also to be appreciated.
