After sharing with you my geometric crochet cowl I thought it might be quite nice to include a tutorial on how to do front- and back- post double crochets (abbreviated to fpdc/bpdc in patterns). These stitches are great ones for adding texture to crochet projects and can add a lot of depth to the finished project making it chunky and giving it some stretch.
I have added the tutorial with lots of photos to help guide you through but if anything is unclear feel free to pop a question in the comments section and i will try to clarify.
So there you have it front- and back-post double crochet. These stitches look great as they are and can help give your work some added depth and texture, or can be used to create some fantastic effects such as ribbing, basket-weave and cabling!
