This is a pillow kit that can be ordered from the Bartlettyarns website, or when visiting the store in Maine or at various fairs where they are vendors. They also do phone sales: 207-683-2251. The pillow kit is complete except for the pillow form, which can be ordered separately.
The yarn is from their own yarn line and is 100% wool. The yarn used for the sheep, Northwoods 2:1, is slightly heavier and more like roving to give the sheep a more “wooly” appearance. After knitting and blocking, sew the bottom and then the side seams, after inserting the pillow form.
