I agree! I think would encourage projects to get done as they are so much smaller. But in my book, not very useful. We have very little wall space that is large enough for a hanging that is over 3' x 3', and I don't want a bunch of wall hangings anyhow.
My solution is to either make more blocks, if the pattern lends itself to that, or add borders. I loved pieced borders, so possibly two or three pieced then one solid. Just depends on the pattern and what it would adapt well to.
