You can start any time you want. Each month a block will be posted, it is your choice if you want to do it or not. If you do the block you can post a pic on picture page so we can ooh and awe. You keep the blocks you make. The most imporant rule is HAVE FUN.
I have attached the direction for the 3 block we have done so far if you look at April 15th BOM is the one we just got.
Hope you have FUN any questions just ask we're all willing to give our 2 cents
