each month someone posts a new block for that month- you check the link- down load the pattern- make the block- there are discussion groups in case you have any problems- and i think they show pictures of their blocks too-
there are a few different ones going on.
if you do one of Rhonda's she will send you templates needed =
some are people working on a particular quilt (like the farmers wife quilt) and sewing-chatting helping each other get through it.
look through the list check the blocks and decide which one you would like to participate in ... and jump right in :)
