The other day I decided to make a neck roll pillow out of some scrap fabric I had. I cut out a good sized recatangle piece of fabric. Then I did a tight hem on the top and bottom of it.
Now here is where I quit taking pictures haha. After that I sewed the long sides together with the fabric inside out. Once that was done I turned it right side out and put ribbon through the wide hemmed sides. I tied the one side tight, knotted it, and pushed the ribbon through. Next, I stuffed it. Now with a neck roll pillow you want to stuff it tight. Once it was stuffed I tied the second ribbon nice and tight, knotted it, and pushed the ribbon through.
