I made a king-size kaleidoscope quilt once, I think the pattern was called keystone kaleidoscope, and I made it for my husband for our 25th anniversary, almost 20 years ago, although it wasn't done until a few years later, it had to age like fine wine I suppose. Anyway, the toughest part, other than making a 110" x 110" quilt top, was dealing with all the bias edges. Would I make another one, probably not, however, some of the QB members have suggested using spray starch to keep the bias edges in line. It's a beautiful quilt top when finished, but as I said dealing with the bias edges had to be done carefully, but it can be done. If it's what you want to make, go for it, to me that's the best way to learn, to stretch our comfort zone, and you'll be happy you did.
