I recently discovered the following site where they email me a link to a new pattern every day. Today was Day 27. So far the blocks are all fairly simple and they are all the same size. You do have to sign up, to receive the email & poke around in the other pages. I found all the blocks without having to wait for the daily email by poking around on it earlier. The link is at the bottom of the page after you login.
