Front Post & Back Post Stitches Explained Deeply

Front post and back post stitches are the mechanism behind nearly every textured crochet fabric. Cables, ribbing, basketweave, waffle stitch — all of them rely on working around the stitch post instead of into the top loops. The technique is simple to describe: instead of inserting the hook under the V at the top of the stitch, you insert it around the vertical body of the stitch from front to back or back to front. That shift in hook placement changes everything about the resulting fabric.

Post stitches project forward or recede backward from the fabric surface. Front post stitches push toward you, creating raised ridges. Back post stitches push away, creating recessed valleys. Alternating them in patterns creates dimensional texture that can mimic knitting, form cables, or produce geometric relief patterns. Understanding post stitches deeply — not just how to make them, but how they behave structurally — unlocks an enormous range of crochet techniques.

This guide covers post stitch mechanics in detail, common mistakes, and how post stitches function within larger textured patterns including overlay crochet. If you need a refresher on the basic stitches that post stitches are built from, the what crochet stitch actually looks like guide provides visual identification.

What Is a Stitch Post?

Every stitch taller than a slip stitch has a post. The post is the vertical body of the stitch — the part between the base (where it connects to the row below) and the V at the top (where the next row is worked). In a double crochet, the post is the tall vertical column. In a half-double crochet, it's the shorter, slightly twisted column. In a treble crochet, it's the elongated column.

When you work a standard stitch, you insert the hook under both loops of the V at the top. The post is not involved in standard stitching. It sits below the working row, part of the completed fabric. Post stitches engage with this previously untouched part of the stitch, wrapping around the post rather than working through the top.

The post's orientation determines how the stitch lies. If you're looking at the right side of the fabric, each stitch post is more visible from the front than the back. Working a stitch around the post from the front side creates a different effect than working around it from the back side. The direction of hook insertion — front-to-back or back-to-front — determines whether the new stitch sits in front of or behind the fabric surface.

Front Post Stitches: Step by Step

A front post double crochet (FPdc) is the most common front post stitch. The technique is the same for any stitch height — front post single crochet, front post treble crochet — only the yarn overs and pull-throughs change.

Step 1: Yarn over as needed for the stitch height. For FPdc, yarn over once.

Step 2: Identify the stitch post you'll work around. The pattern will specify — often the stitch directly below the current position, or a stitch one or two positions to the right or left.

Step 3: Insert the hook from front to back around the entire post. The hook goes in front of the post, then behind it, then emerges on the front side again. The post is now between the hook and the working yarn.

Step 4: Yarn over and pull up a loop. The loop comes from behind the post, up to the height of the current row.

Step 5: Complete the stitch as normal for its type. For FPdc, yarn over, pull through two loops, yarn over, pull through two loops.

The completed stitch sits forward of the fabric surface. It projects toward you, creating a raised ridge. The post it wraps around is partially hidden behind the new stitch. Multiple front post stitches in a row create a horizontal raised band.

Front post stitches tilt the fabric slightly. The wrapping action draws the surrounding stitches inward. A column of front post stitches will be slightly narrower than a column of standard stitches with the same stitch count. Account for this when substituting post stitches into a pattern — the gauge will differ.

Back Post Stitches: Step by Step

A back post double crochet (BPdc) uses the same technique from the opposite direction. The hook enters from the back of the work, wraps around the post, and emerges on the wrong side. From the right side, the stitch recedes backward, creating a recessed valley.

Step 1: Yarn over as needed.

Step 2: Identify the stitch post. Because you'll be working from the back, tilt the fabric slightly toward you or insert the hook from below the post.

Step 3: Insert the hook from back to front around the post. The hook goes behind the work, in front of the post from the back side, then emerges on the wrong side again. From the right-side perspective, the hook wraps behind the post.

Step 4: Yarn over and pull up a loop to current row height.

Step 5: Complete the stitch normally.

The completed stitch recedes from the right side. It pushes backward, creating a depressed line in the fabric. On the wrong side, the stitch sits forward — a back post stitch on the right side is effectively a front post stitch on the wrong side. Back post stitches are commonly used for ribbing because they create the valleys between the raised front post ridges.

Back post stitches tilt the fabric in the opposite direction from front post stitches. Alternating front post and back post stitches in the same row — standard ribbing — creates a fabric that compresses horizontally and stretches to fit. The opposing tilts balance each other, producing the stretchy, recovery-prone fabric characteristic of post stitch ribbing.

Post Stitches in Ribbing

The most common application of post stitches is ribbing. Alternating FPdc and BPdc across a row creates vertical columns of raised (front post) and recessed (back post) stitches. On the next row, you work FPdc into the FPdc posts below and BPdc into the BPdc posts below. The columns stack, creating a fabric that looks and behaves like knitted ribbing.

Standard ribbing combinations:

• FPdc, BPdc alternating (1×1 rib)
• FPdc, FPdc, BPdc, BPdc alternating (2×2 rib)
• FPdc, BPdc, FPdc (1×1 rib with an odd number of stitches, starting and ending with FPdc)

Post stitch ribbing stretches horizontally significantly more than standard crochet. A 2×2 ribbed hat brim stretches to fit a range of head sizes. A ribbed sweater cuff stays snug against the wrist without binding. The stretch comes from the ability of the front post columns to pull apart and the back post valleys to widen. When tension releases, the posts return to their original positions.

For patterns using post stitch ribbing, the easy free crochet ribbed beanie pattern demonstrates ribbing in a wearable project. The principles apply to cuffs, collars, and any edge that needs to grip comfortably.

Post Stitches in Cables

Crochet cables are formed by crossing groups of front post stitches over each other. A standard 6-stitch cable: work 6 FPdc in order. On the cable-crossing row, skip the first 3 posts and work FPdc around posts 4, 5, and 6. Then go back and work FPdc around posts 1, 2, and 3. The two groups have crossed — the second group sits in front of the first group. On subsequent rows, work FPdc around each post in its new position.

Cables require a background of back post or standard stitches to sit against. The front post columns project forward. The background recedes. Without this contrast, the cable blends into the fabric and loses definition. A typical cable panel: 6 FPdc for the cable, flanked by several BPdc or standard stitches on each side to create the recessed background.

Cable crossing creates significant draw-in. A cabled panel is narrower than the same number of standard stitches. Swatch your cable pattern before committing to a project. Measure the gauge of the cabled section separately from the background. The how to fix crochet gauge issues guide covers adjusting for stitch pattern gauge differences.

Post Stitches in Overlay Crochet

Overlay crochet uses front post stitches extensively, often reaching multiple rows below the current row. The technique is the same as standard front post work, but the post being worked around may be buried under subsequent rounds. The hook must navigate past or through overlying stitches to reach the target post.

The reaching motion for deep overlay post stitches requires more control than standard post work. Insert the hook carefully past overlay stitches from earlier rounds. The post you're targeting may be partially hidden. Use the hook tip to gently move overlying stitches aside. Don't force the hook through tight spaces — work it through gradually.

Overlay front post stitches create the tallest, most prominent texture in overlay crochet. Because they wrap around the entire stitch post rather than a single front loop, they project further forward. They're also more structurally secure than front-loop overlay stitches — the post provides a larger, more stable anchor point. For maximum dimensional impact in overlay patterns, front post stitches are the tool of choice.

Common Post Stitch Mistakes

Working into the wrong post: It's easy to accidentally work around the post one stitch to the left or right of the intended target. Count carefully. Identify the correct post by tracing down from the V at the top of the fabric. The post directly below the current stitch position is usually the target. Use a stitch marker if needed.

Missing the post entirely: Working into the space beside the post rather than around it. The stitch should wrap completely around the post. If the hook doesn't go all the way around, the stitch sits awkwardly and doesn't provide the intended texture.

Inconsistent tension: Post stitches are often tighter than standard stitches — the hook path is longer and more cumbersome. Consciously relax post stitches. They should match the size of the surrounding fabric. A common beginner post stitch fabric is noticeably tighter and stiffer.

Post stitch height confusion: A front post single crochet, front post half-double crochet, and front post double crochet are all different heights. Make sure you're working the correct stitch height as specified by the pattern. The "fp" or "bp" prefix only tells you the direction. The stitch abbreviation tells you the height.
