I made mine with cotton knit fabric, just cut out a 4" wide U shape - having the space as wide as you need it for your neck, plus about 2 inches, - and sewed all but 2 inches, stuffed it with pieces of leftover batting, and sewed up the w inch open seam. The knit fabric stretches, so you don't have to worry about making it 3-D, and it washes very well. I hope you can understand my explanation. Good luck.
