This was a BOM kit I bought so long ago I can't remember. The company went under and now I have 3 more blocks to work on that I got. I never got the rest of the blocks. I gave up after a while and now I'm back in the mode. I will put it together best I can. It has a round template for the birdhouse door for each block. I will keep up on it. All you ladies finally inspired me to get back to work! Thanks for your comments. Pam
