When I followed Chele's link, I thought - - man! That page setup looks familiar <g> and when I looked to the top, I found "Quiltville.com" ... so, I went to my favorites, and went to quiltville through my favorites list, trying to get to Tonya's page ... I didn't make it obviously, because I happened to see Bonnie's Happy Scrappy Houses ...
I figured if I had never found Tonya's (of course, I am not a very good explorer) that maybe the link above would also help you find good help in making house blocks. Now, to go back and see how to get to Tonya's page! LOL <wave>
