Thanks everyone, and thanks SuziSew for finding that youtube tutorial, you could make a smaller version of hers adding the rail for propping a book. I used an 8 1/2" wide piece of fabric the same length as the front and back piece, sprayed-glued a piece of high loft poly batting to the back and sewed 5 lines 1/4" apart down each long side, folded it in half (right sides together) and sewed the short edges together, clipped corners, turned it right side out, basted the long raw edges together, centered it, aligning all raw edges between the front and back pieces (at the narrow end of the pillow) and sewed that seam. Hope I didn't make that sound confusing.
