Ms. Teri’s granny square hexagon stuffy designs are incredible. She provides very good instructions and stepwise pictures. The various variations are very reasonably priced, too.

Held Confection yarn double for bigger and middle bear, single str littlest one.
Three different hooks, bigger to smaller hooks, respectively.

A little hard to see the stitches, but having made this design a number of times, not too bad.

85 g, 1.7 sk textured yarn for bigger bear.
80 g, 1.6 sk textured yarn for middle bear.
35 g, 0.7 sk textured yarn for little bear.
