My church block came out a little smaller than the 10" finished size of the posted paper piecing pattern. We were to add onto it to make it 12". Don't ask me why it was small, I checked the 1" mark on my second block before starting and it was correct.
All of the house blocks I used in the design are 12". It is not the REAL blocks that will be posted for the BOM since I do not know what they will be each month.
