I have received emails from people saying they have looked for a pattern for U-shaped neck pillows and have found nothing. They saw the one on my site http://paturydesign.hotusa.org/index.htm
and have ask me if I would send them the pattern I made. I did but I also decided to add this pattern to my Tips& Pattern page on my site for free to copy.
I made a PDF file of a U-shaped neck pillow, so the visitors of my site can download the PDF file containing the group of images they can print on 8.5 x 11 paper and paste together to make a full size. http://paturydesign.hotusa.org/
