The 3D Cluster Stitch is a thick, double-sided pattern crocheted with offset front post double crochet clusters to give a 3D effect to your work. When crocheted in 2 colors, each side is colored differently, one color on one side, the other color on the other side. It works great for baby blankets, wearables, hats and scarves.

The pattern is a two-row repeat and after making a few rows, you won’t need to reference the pattern anymore, you will know exactly where each stitch goes.

If you are using multiple colors with this pattern, you will need to cut the yarn at the end of every row, but the end result is well worth it.
