This striking crochet stitch features a raised diamond pattern on a solid background. It would be great for just about any project; hats, scarves, cozy throw blankets and more.

The main component of this crochet stitch is the front post treble crochet 2 together stitch. This stitch is a mouthful to say and sounds more complicated than it is. Usually when we see 2 stitches worked together they are either done in the same stitch (like you would make a cluster) or in 2 stitches next to each other to to make a decrease in your project.

In this version, we are not only working them around the post of a stitch we are also splitting them up to form a triangle shape. When we work these triangles row after row they form this diamond trellis pattern.

The most challenging part of this stitch is making that first row of post stitches because instead of building on previous post stitches you will work around the single crochets from row 1. After you get that row completed the rest is smooth sailing. My best tip is to make sure you post stitches aren’t too tight. This will pull your project and create a lot of curling.

  • Ch 1 and 2 do not count as stitch
  • Leave stitch behind each Fptr and fptr2tog unworked.
  • All post stitches are worked 2 rows below
  • Starting in row 5 all front post stitches are worked around post stitches from previous rows. This creates a diamond pattern that lies on top of the background.

2024 Crochet Along: Square 13

We are working on block 13 of our 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.

  • 146 yds worsted weight yarn, Red Heart Super Saver used in sample
  •  5.5 mm crochet hook
  • Scissors + Yarn Needle
  • Gauge: 7 sts x 5 rows = 2 in in pattern stitch
  • Finished Size: 11.5 x 11.5 in
    • After blocking: 12 x 12 in

This is what I did:

  • Ch 36 to start
  • Follow stitch instructions above until your square is the desired size. For me this was 29 rows. You may need more or less.
  • After final row do not finish off, move on to border.

Border Instructions: Do not finish off, working on front side of square, 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 35 stitches)

Save it on Pinterest and crochet it later!

  1. I can’t wait to make this block. I’ve been catching up on the previous 12 blocks and learning so much. I have had to “un stitch “ a lot of stitches, but practice practice practice! Thank you,
