Craftingback post single crochet
Description
A textured crochet stitch worked around the vertical post of a stitch from the previous row, inserting the hook from the back side.
Detailed explanation
The back post single crochet (bpsc) is a technique used to add texture, create ribbing, or form a raised ridge effect in crochet fabric. Instead of working into the top loops, the hook is inserted around the vertical body (post) of the stitch below, entering from the wrong side of the work. This action pulls the post backward while pushing the top loops forward, creating a distinct horizontal ridge often used in hat brims, borders, and structural patterns.
