C2C crochet heart hat pattern

This C2C crochet heart hat pattern features one bold heart centered on the front for a clean, modern look that really stands out. The heart is created using simple color changes while working the hat flat in corner-to-corner crochet, then seamed and finished with a cozy brim and optional pom pom.

Designed for toddler, child, and adult sizes, this pattern is a fun way to explore C2C on a smaller project while still creating a hat that looks great and fits comfortably. It’s a great option for everyday wear, thoughtful gifts, or adding a handmade touch to seasonal outfits.

Why you’ll love this pattern

• Great C2C practice — A smaller project that’s perfect for building confidence with corner-to-corner crochet.
• Three sizes included — Toddler, child, and adult sizes make it easy to crochet for the whole family.
• Customizable colors — Choose classic Valentine colors or modern neutrals to match any style.

How this C2C heart hat is constructed

This C2C crochet heart hat is worked diagonally using standard C2C blocks made with chains and double crochet stitches. The main panel is crocheted flat, following either a color graph or written color instructions to form the heart design.

Once the panel is complete, the short ends are seamed together to create a tube, forming a corner-to-corner crochet hat with the heart centered on the front. The top of the hat is closed by working in the round, and a separate ribbed brim is sewn onto the bottom edge. The hat is finished with an optional pom pom.

This construction keeps the heart design crisp while allowing for easy sizing adjustments.

What is corner-to-corner crochet (C2C)?

Corner-to-corner crochet (also called C2C) is a technique where you crochet diagonally instead of in traditional rows. The design is built using small blocks made of chains and double crochet stitches, starting in one corner and increasing row by row to shape the piece.

For this C2C heart hat, the corner-to-corner method makes it easy to create a bold heart design with clean color changes, while still keeping the construction simple and repeatable. It’s a fun way to add visual interest without complicated stitch work.
