Seat Belt Belt

Step 2 Size at your leisure

I decided to leave on some extra length in the belt so that I could take the stitches out and resize it if I wanted later. I measured the belt around my waist, and marked a line on the longer strap where it overlapped with the shorter. I folded over the extra, and sewed it onto the other strap, then folded over the little tail that remained, and put a line of stitches into it.
