This garter stitch ball is about 4 or 4.5 inches in diameter — about the size of a grapefruit —
and is shaped by short rows. It’s a good for using up odds and ends of yarns of different colors.
Each section takes about 4 yards of yarn.
4-ply (worsted weight) knitting yarn, one or two or more colors
Pair of #4 (US) needles
Polyester fiber filling or old nylon stockings or other stuffing
Note that the needles are small for the size of the yarn.
This makes a dense fabric so the filling won’t show through
