DH made 3 pressing bars for me from one 1" dowel. He ripped a 36" dowel in half. Left one at 36" and cut the other 24" & 12". Drilled a hole in each and I hung them on my wall.
They are invaluable when pressing open a seam in any fabric that would show an imprint. Iron only touches at the top of the rounded part.
Short one very handy for pressing pillow seams as it can be put inside & moved around.
