There are twelve blocks, I believe. I have 10 of them but, like you, refuse to go back and continue to look. This is my first time to participate and I found the whole experience very frustrating. The two blocks that I do not have are: House with Red Door and Squatty Pine. I would be happy to share any of mine with you that you may not have. If you have either or both of the two that I didn't find, I would appreciate getting those. Thanks. Since this post is several days old, I will PM you.
