I make a 3 part hanging sleeve and try to keep the middle section always at 15" in width. (leave approx 1" in between sewn sections. ) I buy a piece of thin wood approx. ¼" x 1" and cut it to measure the width of my wallhanging. Then find the center and measure out 7 ½" on both sides & drill holes. Hammer nails with heads 15" apart into the wall where you want to hang it. Slip the wood into the sleeve & the holes should match up with the openings on the sleeve, now place the holes onto the nail heads & your wallhanging will hang nice & close to the wall, and the top will be smooth. (I'm not sure but I think this idea may have come from Ami Simms originally)
Edited to add: if you do this you can interchange what ever wallhanging you want to without pounding nails into the walls for different widths of wallhangings.
