How to Crochet a Reversible Post Stitch Fabric
By Kathryn Vercillo of Crochet Concupiscence
This easy tutorial shows you how to alternate front post and back post crochet stitches to create a thick, textured, reversible fabric. It’s perfect for anytime you want a great padded fabric; for example it could be used to make gadget cozies, weighted blankets or even a very thick winter scarf.
Crochet an odd-numbered starting chain. This example is a chain 23.
Dc in third chain from hook and every chain across. Turn.
Chain 3 (counts as first double crochet). Skip first dc, * fpdc around next dc, bpdc around next dc. Repeat from * to end. Dc in top of last dc. Turn.
Tip: The last dc is going to be slightly taller than the rest of the row (since the other stitches are worked around the post). If this bothers you an alternative is to dc in the second chain of the dc instead of the top chain.
Chain 3 (count as dc). Skip first dc. * fpdc around fpdc, bpdc around bpdc. Repeat from * to end. Dc in top of last dc. Turn.
Repeat Step 4 to the desired length of project.
This stitch will work with any hook and yarn size but of course the fabric will be denser with thicker yarn. This example uses Red Heart Super Tweed and I sized crochet hook.
