My daughter complains about her seat belt rubbing against her chest and neck. We usually just pull her shirt up or turn her collar up to protect her skin. I finally had an ah ha moment and made her a set of seat belt covers. This was a quickie accomplished over lunch.
These are for my daughter
What you'll need:
2pcs of each - 5 1/2 x 4 flannel (or any other fabric you like), batting, double sided quilted fabric (you can double up on the batting if you want to use another fabric).
6 in of velcro
Thread
Lay the flannel wrong side down, then quilted fabric, and batting. Sew around (1/4 in seam) leaving a 2 inch open to turn inside out. Clip corners and turn inside out. Sew 2 inch opening shut. Attach velcro and you're done!
I made made another set for my son using 5 1/2 x 5 measurements instead.
***Update*** - For adult sized, use 7.5 x 7.5 squares.
