Occasionally, you might run into a molding that absolutely can't be done with one big piece of fabric. Then you will have to make a pattern and cut the fabric in 2 pieces with a seam at the bottom corners. Vince's (302 Z28) moldings were like that, which is the reason he was having so much trouble doing them himself. Here's how I covered his three moldings. They all were basically alike, made of fiberglass and coming to right angles at the bottom outside corners. The first pic is obviously the unfinished molding. The second pic shows the cardboard pattern I made that fit the corner. Then I just measured in between the corners and added a 1/2" seam allowance. The vinyl stretches side to side, so I cut it about 3/4" shorter than full size to stretch it into place. The 3rd pic shows the seam from the outside. The 4th pic is the seam I sewed from the inside. The last pic shows how closely I cut next to the seam so there would be no bulges in the corners.
No one lives forever, the trick is creating something that will.
