In the first file for the BOM 2011, Ruffled Roses, a house block is used to practice paper piecing. If that's what you're looking for, you better hurry downloading those files, because it will not be there much longer

In show 711 she shows how to piece a house block with flip and sew. Don't remember her doing one with paper piecing.

Speaking of foundation piecing houses: a Dutch quilter (Jeanneke)is starting a 2012 Block of the Day challenge to make 366 house blocks in 2012 and has a worldwide following at 800+ strong last I looked; several in my local guild are planning on participating. Here is a link to her project: http://iloapp.jeanneke.com/blog/www?ShowFile&doc=1323930819.pdf and to her blog: http://buildinghousesfromscraps.blogspot.com/

I'm not planning on participating, although I might make a few of the houses at some point....too many UFOs already to add another to the list! Nancy

Could it be show 212? There is a schoolhouse mentioned and the pattern can be bought from the project page:

Good luck
