I found this cool no-sew stuff and wanted to try it out.
For this project all you need is, fabric, an Iron, Batting, Velcro, and either a sewing machine or no-sew iron on adhesive. If I had my sewing machine I would probably like to use that instead of the no sew stuff. It worked just fine, it just took a lot longer to iron on than it would take to sew it together. You are basically making a mini blanket.
First I cut out some scrap fabric into 7 by 7 inch pieces. You might need to measure your straps on your carseat for the exact measurements. You need 2 pieces of fabric for one Strap Protector. Iron the edges, and place a thin piece of scrap batting(you can always use extra fabric if you don't have any batting). Ironed on the edges of the no-sew pieces except for one side which will be covered by Velcro so you don't need to bother with that one side. Iron all fabric together. Use the directions from the no-sew container.
Put the Velcro on and you are just about done.
All you need to do it put it on your car seat and there you have it. Just repeat the same thing for another one. Now my daughter's neck is protected from the straps cutting her neck.
Any questions, let me know. I am happy to help.
