The snail hand puppet is designed to fit a childs hand, but it also fits smaller adult hands. You should know how to knit in rounds and be familiar with increases/decreases.
You have to graft (kitchener stitch), do short rows and make an I-cord. A tutorial (with pictures) is included in the pattern instructions.
To make this handpuppet you'll need:
1 set of dpns size 3,5/4mm; US 4-6 depending on your gauge
1 tapestry needle
1 savety pin
yarn in light brown and brown
23 stitches and 30 rows = 4 inches in stockinette
