This is all I have of this one done but the top will be aproximately 38" square when done and I need it to be 40" x 52" square. How can I accomplish this without making it look bad? I have no material in my stash to match it and don't have the money to go buy any. The brown is a mottled brown and the white is some white on white with flowers on it. Please help! Am also posting a link to here under main.
