Wow -- you have some gorgeous fabric there!!!
Sometimes I piece backings but I don't really like to do it -- especially with different fabric. More work and then it looks wonky if the seams are straight, etc. after quilting. On the 120" sq. quilt I made for my daughter, I used several different fabrics for the backing as I couldn't find anything to buy that was big enough. Took me frigging forever to get it right..... :evil: :D :D
