That is one beautiful quilt. The price for buying the pattern is expensive but not for what you get. If you design your own, you can use any 6" insert block you like; you can even use a different house pattern, although as a single block in a gift quilt, you may want to stick closely to the original. Whatever you decide, please share a photo of the completed block. From what I've seen so far, it will be stunning. Joyce in Delaware
