This edging features tall shell stitches built using treble crochets, and an interesting two-color repeat. The pattern integrates single crochet and surface crochet slip stitches as well.

The pattern includes instructions for turning corners, enabling you to use the edging on afghansbaby blankets, linens, pillows, and other projects that are shaped like squares and / or rectangles.

Edging Instructions

You will need two different colors of yarn or thread -- color A and color B. It would be good if both colors A and B contrast with each other and also with the project you are adding the edging to. The colors should also work well together and be harmonious with each other.

This edging is a multiple of 14 + 1 sts.

Row or Round 1: Begin using color A. [Work 1 sc st in ea of the next 9 sts. Skip next 2 sts, 7 tr in next st, skip next 2 sts.] Rep the sequence in brackets all the way across the row. sc in last st in row. If you are working a project with corners, when you get to a corner, ch 2 to turn the corner and then keep working in pattern. At the end of the row / round, change colors to color B.

Row or Round 2: [Work 1 sc in ea of the next 2 sts. Skip next 2 sts, 7 tr in next st, skip next 2 sts, sc in next st.

Then work 1 surface crochet sl st into ea of the next 7 sts in the project below row 1.] Rep the sequence in brackets all the way across.

When you get to a corner, you should be able to just rotate the work and keep going. If you have to, you could always sneak an extra slip stitch in there, but I didn't find that necessary when working my project sample.

Page 5 of this book features a pattern for a baby's shell stitch lap pad, which is crocheted using a shell stitch pattern that was influential in my early efforts to learn about crocheting shells. I often refer to this pattern for inspiration when I am working with crocheted shells.
