I join the siggie block swap who is an international swap now.
You can make blocks from your scraps. My fabrics are from my lqs but if anyone want to use some wallmart fabrics I don't care at all.
What I ask for is that you make your swap blocks with love. Even if your quiltwork isn't so beautiful( i'm not a good quilter also) it doesn't matter to me. The only thing I care about is that people wants to make u a block and send it for you. Every block that will fall on my doormat will give me a big smile on my face.
Taking care for each other, I think thats what swapping really means.
