Just as lighthouses help guide journeying ships at sea back home, front posts help guide your knitting needle to where it should go for complex patterns.
In this advanced crochet tutorial, Mikey from Mikeyssmail takes you through using the Front Posts. Fancy patterns talk about this in patterns. They call it FPDC = Front Post Double Crochet. Mikey shows you how to crochet and where to place your crochet hook in this tutorial. This is used in fancy patterns like Zig Zag Crochet Stitch Patterns and Ripple Stitch Patterns. This tutorial is the left hand version.
