Since all of the house patterns will be posted in the BOM thread, and I will be changing the patten to include each one as it is posted, then all that's needed is all the extra parts.
Everything is based on 3", 6", 9", 12", etc. and I've tried to keep in mind ease of piecing sections together, I don't think it will be too hard.
I can probably do a pattern just of the extra parts and export it to PDF. That will take quite awhile because I need to print each block to PDF but it's do-able.
