I have made something like that. Don't know if this is what you want but here goes. I cut my fabric handle 6 times wider than finished size (usually about 6 inches. ) I fold it in half lengthwise and press, then fold the open side one inch towards the center and press, then fold the folded size on top and press and sew down. Works easily and the extra fabric is really needed for a purse handle. I used batting inside with this also. Does this make sense?
