How to Identify Any Crochet Stitch from a Photo (Stitch Scanner Guide)

You see a gorgeous textured stitch on a blanket at a craft fair. You screenshot a crochet bag from Instagram. You find a vintage sweater at a thrift store and want to recreate the fabric. The problem: you have no idea what stitch that is, and reverse-engineering it from a photo manually can take hours.

How the Stitch Scanner Works

YarnCro's stitch scanner analyses the photo you upload, identifies the stitch or stitch combination visible in the fabric, searches its library of 1M+ professional crochet instructions for the matching technique, and returns:

• The exact stitch name (e.g. "extended single crochet moss stitch" or "spike stitch linen stitch")
• Difficulty rating (beginner / intermediate / advanced)
• Recommended hook size and yarn weight
• Row-by-row swatch instructions you can test immediately
• Notes on variations and common uses

Getting the Best Results

Photo quality matters

The scanner works best with:

• Clear, sharp photos — out of focus images return less precise results
• Good lighting — natural daylight or a ring light beats flash photography
• Close-up shots that clearly show the stitch texture, ideally filling most of the frame
• A contrasting background — dark yarn on dark surface makes the texture harder to read

Single-stitch sections

If the item uses multiple stitch patterns (e.g. a ribbed brim + body fabric), crop to show just the stitch you're trying to identify. Mixed stitch areas produce less confident results.

Common Stitches It Identifies Well

• Granny square variations
• Shell stitch and fan stitch
• Bobble and popcorn stitches
• Chevron and ripple patterns
• Tunisian stitches (Tunisian simple, Tunisian smock)
• Linen stitch and moss stitch
• C2C (corner to corner)
• Waffle stitch and basketweave
• V-stitch and V-stitch variations

Stitches That Are Harder to Identify

Very complex overlay stitch patterns (like tapestry crochet) can sometimes be misidentified as simpler stitches when the photo doesn't show enough repeats. For best results with complex color work, upload a photo that shows at least 3–4 full pattern repeats.

What To Do With the Result

Once you have the stitch identified, the scanner returns a swatch tutorial you can test with scrap yarn before committing to your main project. You can also paste the stitch name into the pattern generator with a full project description to get a complete pattern built around it.

Frequently Asked Questions

Can it identify knitting stitches?

Yes — the scanner identifies both crochet and knitting stitches from photos. Select "Knitting" in the scanner if you know the item is knitted.

What if I upload a PDF or screenshot of a pattern?

Use the Stitch Assistant for PDF questions — it's designed for document Q&A. The scanner works best with photos of actual finished fabric.
