Lavender Haze Patchwork Coatigan: Free Crochet Pattern
Introduction
The Lavender Haze Patchwork Coatigan is a cozy, boxy layer that anyone can make — even if you've never joined a granny square before. It's built from 62 classic granny squares in soft lavender and mint, arranged in bold color blocks so the finished coatigan looks modern and intentional rather than busy. The open, lacy square texture keeps it light and drapey, while plain single-crochet bands at the neck, hem and cuffs give it a clean, polished edge. Slip it on over jeans and a tee and it feels like a favorite cardigan with a little extra warmth and a lot of personality.

Gauge
One granny square = 6 x 6″ [15 x 15 cm]. Work one square in the pattern below and measure it flat; if it's smaller than 6″, go up a hook size, and if it's larger, go down a hook size.
Tips Before You Start
- Make one practice square first and measure it — square size controls the whole fit, so getting gauge right before you make 62 saves time.
- Keep your color order consistent: every square is lavender (R1), mint (R2), lavender (R3), mint (R4), lavender (R5).
- Lay out all your finished squares on the floor in the panel arrangement before seaming so you can check the color blocks at a glance.
- Leave a long tail (about 8″) when fastening off each round — those tails are handy for whipstitching later.

Assembly and Finishing
Arrange all squares following the layout above. Sew squares together with whipstitch using matching yarn, joining squares into strips first, then joining the strips into panels. Join the back to the fronts at the shoulders, then attach the sleeves at the shoulders and sides as part of the patchwork assembly. Work the neck band, hem band and cuffs as described. Weave in all ends. Block lightly by misting with water and pinning to measurements, then let dry flat.
Pro Tips and Variations
- Swap mint for another contrast color to change the mood — a soft gray or cream keeps it neutral.
- Add a single row of sc along the front opening edges for a slightly more finished look.
- Make it longer by adding one more row of squares to each panel (allow extra yarn).
