a Seatbelt Protector
Every time I get in the car, the seatbelt seems to cut right into my neck, I'm 5 foot 2 and a half inches tall and quite short-waisted. I used to just slip the shoulder harness down out of the way, but that's not too safe. I've made these for friends and included them in a gift set with posture reminders and reusable makeup pads.
These are super easy and sew up fast, all you need is:
an orphan block, fat quarter, or approximately 10 x 10' of fabric any woven fabric, upholstery, denim, or something from your stash of quilting cotton.
6-8 inches of velcro
