Just wondering if you all could help me. I showed my dbf the jelly roll quilt I'm working on for my mom and he said he liked it. Then went on to say that he really likes the kind of quilts my grandma used to make you know the ones that have all kinds of different fabrics that come from any where clothing other blankets etc. So I decided I wanted to make him a quilt like grandma used to make. What I'm wondering is how many 4 1/2 inch squares does it take to make a lap quilt? Thanks for helping :)
