Free intarsia vest pattern 🔴 Chroma Vest by Knit Sis

30 September, 2025

Dare to knit the Chroma Vest, a modern, colorful and free intarsia vest pattern designed by Knit Sis @knitterssisters. Knit this wide vest with a V-neckline in your favorite color combination of Katia Super Merino.

This pattern combines knitting flat and in the round: the body is worked flat, with the intarsia technique only on the front, and the waist and armhole ribbing is knit in the round. Follow the chart and row-by-row instructions to enjoy a geometric design with a retro vibe that is completely customizable.

Knit Sis: colorful creativity

Knit Sis are Lenny and Louise, two sisters who are passionate about knitting and who grew up in a family where needles and yarn were part of day-to-day life. When they were little, they learned how to knit with their grandmother and aunt and naturally wanted to share their passion by creating their own designs.

Each design they come up with—cardigans, sweaters, tops and vests—are designed to combine comfort, style and the pleasure of knitting. They love to play with colors, textures and geometric shapes to create unique, cheerful and accessible pieces. For them, knitting is a way of reconnecting with yourself and enjoying the creative process of making something with your hands.

Chroma Vest: color and geometry with the intarsia technique

Chroma is a vest with a colorful geometric design that celebrates textile art. Use the intarsia technique to draw a big red circle, a vertical yellow stripe and a blue and lilac background. A striking pattern where each stitch conveys creativity.
