I made one of these several years ago and remember watching a tutorial that was a big help. The one thing that I definitely remember was the person commenting about the number of needles she used if she wasn't careful. Be sure those pellets are out of the way!!! I used a very tightly woven sheet, hoping then it would be covered with something like a duvet (spelling?) so it wouldn't need laundering very often. Sure wouldn't want those pellets spilling out in the machines or melting in a dryer. As I recall, I bought pellets at Hobby Lobby, using their 40% coupon.
