dottie dodge, April will send you an email with the names, addresses, a list to check off when you sent fabric, fabric received, when you finished the block, when you mailed the block, and when you received your block back. April will have a name for each group and she will start a thread for that group. Side swaps are between 2 people that might not be in a certain group. For instance, say you and I are not in the same group and you wanted to make an extra block, you may have said you would do a side swap and I contact you, then we would send each other a f8 and make a block and send it back to the person. Mail the blocks back when you finish them and mark it off your list. Take a picture of the blocks you make and the blocks you receive. Post pictures when you receive a block. If your partners do not have a camera, they may ask you to post a picture after they receive it, this way, they get the surprise of seeing the block first. Most of the time, you can keep the extra fabric, but if someone asks for the left over fabric back,, send it back to them. Hope this helps.
