Toni,
Generally the BOMs are posted on the 1st and 15th.
While you're waiting for the 15th pick another block from the old ones listed here. They're all great blocks. When you've made a block be sure to post a picture in the appropriate month for us all to look at. Seeing the different variations is almost as much fun as building the block itself. This BOM is addicting isn't it? The great thing about this BOM project is that it's here all the time and there is no expiration date on any block.
