Overlay and Mosaic Crochet: Creating Pictures in Yarn

What Makes These Techniques Special

Overlay crochet and mosaic crochet both create pictures using only two colours per row, worked in alternating sets of rows. Instead of switching yarn constantly, you carry the unused colour along the top of your stitches and work front post or back post stitches through previous rows to build raised, sculptural motifs.

Overlay Crochet

This technique uses front post stitches worked into rows below the current one, creating a textured, almost embroidered look. It's popular for animals, flowers, and detailed scenes.

Mosaic Crochet

Mosaic works more like colourwork knitting, using simple stitches (often single or double crochet) and skipped stitches to form geometric patterns and pixel-style images.

Tips Before You Start

• Practice with a small chart first, like a heart or star
• Keep tension even, since tight carried yarn puckers the fabric
• Use a firm yarn (cotton or wool blend) for crisp stitch definition
• Block your finished piece to flatten curling edges

Both techniques reward patience. Start with a simple two-colour chart, follow the row-by-row instructions closely, and don't worry if your first attempt looks a little wobbly. The picture usually reveals itself only once you've completed several rows.
