This is from a pattern by Old Toy Knitting Shop basically made up of squares & rectangles. The pattern specifies double knitting wool. I used moss coloured 4 ply for my first attempt. Then my husband said he needed one as well. His is stone coloured, & has LED eyes which light up when a magnet in the tail (a large triangle folded in half to hold it) touches a switch on the battery sewn inside the body.
