Lucy,
I had problems one night with the block patterns not showing up, and then it said I had all 12. When I checked the member area, under "visited" shops, I found all the PDFS that you could download in case you missed them. Up at the top it should say "blocks found" and then scroll down and you should be able to see them (if you were having the same trouble as I was) Check it out, because they may be there.
