The finished shell stitch blanket.

Materials and yarn planning

Yarns we’ve reviewed that suit it: Knit Picks Dishie Cone yarn, Lion Brand 24/7 Cotton worsted yarn, Paintbox Yarns Cotton Aran. For the hook, choose by size and handle.

For an exact figure in your own yarn, weigh a washed swatch in the pattern stitch: the weighed-swatch yarn calculator scales it to each flat panel or strip. Allow a little more for seams, edging and tails.

Finished size and gauge

Each shell repeat is 6 stitches wide. With S stitches per 10 cm, the blanket is about 121 × 10 ÷ S cm wide. Add or remove 6 chains to change the width by one shell.

The gauge calculator compares your swatch with the pattern. A stitch name you do not know is in the abbreviation chart; a UK pattern’s names are in the US/UK term reference.
