When I'm not driving, of course.
I'll be using this around the house as well. I may even make another for a back up. I have quite a bit of neck pain and I usually deal with it, but I think this will help me a lot.
I used this tutorial here. The link has the .pdf pattern and the sewing instructions. This project took me about 2 hours from cutting the fabric to the last stitch. It was fun to make, it fits well, and is super comfortable. I used cotton fabric from my stash and an almost 12 oz. bag of fiberfill which I bought yesterday.
Using stash fabric and a $4.00 bag of fiberfill, this would make a nice gift for someone.
