There are actually a few on this site. Last year I was part of the Star BOM--not finished yet but have 9 of my 12 done. They have the archives for the past 3 year I think. This year there are a few going on as well but you will need to buy a book to join in the 50 stars, but that being said the book is fairly inexpensive and the download is even less. QuiltersCache.com has TONS of free blocks you could just pick a different one everyone month and make your own sampler pattern. Just remember no matter which direction you go we WANT to see pictures and you should have lots of fun!!
