My son recently moved into a high-rise condo and has asked for a new quilt. I purchased a great wall hanging titled, "Concrete Jungle," because it reminded me of high-rise buildings. How can I make a quilt out of this wall hanging? I thought I could make the wall hanging, but add enough of the background fabric all around it to make it a quilt. The wall hanging is 32 in. by 20 1/4 in. The quilt needs to be 72 in. by 88 in. Any thoughts on how to make a quilt out of this?
