The Treble Shell Crochet Stitch is a variation of the shell stitch in crochet. This version of the shell stitch utilizes the treble crochet stitch to create dramatic shells that are taller and bolder than the usual shell stitches worked using double crochet stitches. This stitch would be useful for crocheting limitless numbers of projects including home decor items such as blankets, pillows and placemats or wearable accessories such as scarves, cowls and hats.
Supplies You Will Need for Working the Treble Shell Crochet Stitch:
Yarn, Fiber or Crochet Thread: You can crochet this stitch using just about any yarn or thread you want to. In the example pictured here, I’ve used three different yarn colors. The colors in the sample swatch are as follows:
- Color A: Strawberry, the vibrant pink colored yarn
- Color B: Autumn Maize, the tan colored yarn
- Color C: Chocolate, the dark brown colored yarn
Feel free to substitute other yarns.
To crochet the striped design as photographed, work a row of color A, followed by a row of color B, followed by a row of color C. Then begin the pattern over with another row of color A, then B, then C, repeating this color sequence until the crocheted piece is the length you want it to be.
This stitch doesn’t have to be multicolored or striped; you can omit the color changes to make a solid-colored fabric, or you can create alternate colorways using any number of colors.
To crochet sample swatch pictured here, I used a size I / 5.5 mm crochet hook, which works well with worsted weight yarn. If you use a different yarn weight, you’ll want to choose an appropriate hook for the yarn or thread you’ve chosen. Check your yarn label for a suggested hook size if you aren’t sure which hook to use.

If you want to create a multicolored fabric, you’ll need to know how to change colors. Before you complete the last step of the last stitch in each row, change to the next color you want to work with.

How to Do Treble Shell Crochet Stitch:
Crochet a length of chain stitches that works with the stitch multiple mentioned above.
R 1: HDC in the 3rd ch from your hook. [Skip 3 chs. Work 7 tr in next ch. Skip next 3 chs. Hdc in next ch.] Rep the instructions in brackets all the way across the R.
R 2: Ch 4, turn. The t-ch counts as the 1st tr in the row. Work 3 more tr into the same st to create a half-shell. [hdc in the center of the next shell, then work 7 tr into the next hdc.] Rep the instructions in brackets all the way across the R. At the end of the R, hdc in the center of the last shell, then work 4 tr in the last hdc.
R 3: Ch 2, turn. Hdc in first st. [Work 7 tr in next hdc st. hdc in the center of the next shell.] Rep the instructions in brackets all the way across the R. End the row by working 7 tr into the next hdc, then working a hdc into the t-ch.
To continue working in the established pattern, simply rep rows 2 and 3.
