The Crochet Interlocking Cluster Stitch is a beautiful stitch pattern that combines alternating rows of three dc “shells” and dc3tog clusters to create an eye catching interlocking design. The clusters sit beside one another, forming a textured fabric with small decorative openings throughout.
Despite the intricate appearance, this stitch uses familiar crochet techniques and a simple three stitch pattern repeat. It’s a lovely choice for crocheters who enjoy working with clusters and shells but want to try something a little different.
About the Crochet Interlocking Cluster Stitch
The crochet Interlocking Cluster Stitch gets its name from the way the alternating rows of shells and clusters appear to fit together.
One row features groups of three double crochets worked into the same stitch, creating small fan shaped shells. The following row uses dc3tog clusters, bringing three stitches together at the top.
By staggering these two stitch combinations, the pattern develops a distinctive interlocking appearance. Small chain spaces separate the clusters adding a delicate, slightly open texture to the finished fabric.
