Once upon a time I ordered a 50 lb. box of fiber fill from Factory Direct. At the time I was really into making animals. Needless to say, I still have most of the stuffing & it sure comes in handy, at this time in my life, as I live over 1 hr. travel time to the closest fabric store.
I used Simplicity pattern called "CAROLS ZOO" 2 pc pattern. each front is 1/2 of front. Each back is 1/2 of back. You cut 2 fronts & 2 backs, sew center seams- than sew front to back. Very easy. Just read all instructions carefully. If you larger animals, I took mine to the local copier & had them enlarged. Also had them made smaller than pattern pieces.
Good luck to you. I enjoyed making mine.
