INTRODUCTION

Isosceles

beauty shotby

Tangy

Geometry rulez. Isosceles is the ultimate expression of the two things I love most about making knitwear: math and design. In this pullover tunic sweater, the stranded triangles begin dominantly black and transition like magic to white. To further the triangular sentiment, single color textured triangles are scattered across the upper part of body and sleeves. It’s like a party for triangles on this sweater, yo.

This sweater is knit seamlessly from the bottom up. The lower portion of Sleeves and Body employ the stranded knitting technique. For rounds that use both MC and CC1, carry both colors along throughout the round. For rounds that only use a single color, leave the unused color hanging at the beginning of the round. Trap any floats longer than 5 stitches long.
