The 3d slanted shell crochet stitch is a reversible highly textured stitch with a one-row repeat.

I had such a hard time coming up with a name for this stitch! I’ve seen it called the pistachio stitch and the ocean wave stitch. This stitch is very similar to the tulip stitch, but it starts differently and has a front post single crochet instead of a standard single crochet. So I didn’t want to to call it the 3d tulip stitch.

I finally landed on the 3d slanted shell stitch. This is one of the different names I found for the tulip stitch when I was writing up that tutorial.

2024 Crochet Along: Square 9

This is the 9th stitch of the Terrific Textures Crochet Along! This is a year-long CAL running here on The Unraveled Mitten, we are learning a new textured crochet stitch every week other week. Around the end of October, we will join our stitch sampler squares into a cozy blanket.

You can find more info here.

Pre-Order the Entire Pattern Here

You can purchase a pre-order of the Terrific Textures CAL in my shops. Each time a square is released you will automatically receive the PDF copy of that pattern.

You can find written instructions for this stitch above. You’ll notice that the instructions are written so you can use this stitch in other places besides this CAL. You can find my notes on how I made my 12-inch square listed below.

  •  130 yds worsted weight yarn, Red Heart Super Saver used in sample
  •  5.5 mm crochet hook
  • Gauge: 2 shells x 5 rows = 2 in
    • Use pattern stitch
    • 1 shell = (2d, ch 2) in ch-2 space, fpsc in next dc.
  • Finished Size: 11 x 11 in (before blocking)
    • After blocking: 12 x 12 in
    • Remember a little too small is better than too big. My squares end up being anywhere from 11.5-12 inches.

This is what I did:

  • Ch 37 to start
  • Follow stitch instructions above until your square is the desired size, being sure to end on an odd row. For me this was 28 rows.
  • It may measure smaller before adding the border, this is normal. Adding the border round will stretch it out a bit. 
  • After final row do not finish off, move on to border.

Border Instructions: Do not finish off, ch 1, sc evenly around placing (sc, ch 2 sc) in each corner space. Join to top of 1st sc with sl st. Finish off weave in ends. Block to 12 inches. (Each side should have 36 stitches)

Save it on Pinterest and crochet it later!

  1. Heather,

    I am an experienced croheter. I have started this three times and it keep looking like ruffles and curling into a circle like there are too many stitches. Could you post a tutorial video so that I can watch what you are doing?
