Iíve decided that I am going to attempt make a Karo step underquilt! It seems that the boxed end would be easier than the differential. (If my understanding of differential is correct?)
Could anyone explain the process of making the ends of a quilt boxed? Does this refer solely to the hems being stitched to form a box  all the way around or are the ends reinforced with an additional piece of cloth? Thanks for any responses!
