Modular Triangles

This “Knitting Technique” will teach you how to get started knitting patchwork or modular Equilateral Triangles. This is an awesome shape and when joined with other triangles the possibilities are endless!  

The best way to learn about this super fun (and easy) technique is to pull out your stash and experiment. Once you get started, you’ll want to keep on going!

To knit an equilateral triangle, work a double decrease three rows out of every four rows.

 The Basics: 

  • You can knit your modular triangles as big or small as you like. All you need to know is that you will cast on an equal number of stitches from  “A” to “B” and also from “B” to “C” plus you will add 1 corner stitch. See diagram below.
  • The modular triangles are knit individually; however they are joined as you knit. In other words, you won’t end up with a bunch of triangles that you have to sew together at the end because the triangles are joined while you are knitting.

co—cast on
col – color
k2tog – knit 2 together
k3tog—knit 3 together
sl – slip
sl1 – slip 1
sl1p—slip 1 purlwise
p – purl
p3tog – purl 3 together
tbl—through back loop
wyif—with yarn in front 

Let’s get started: 

All rows begin and end with edge stitches. This is included in the instructions.

Row 1: with col 1, cast on 33 sts (16 sts from “A” to “B” and 16 sts from “B” to “C” plus 1 corner stitch)
Row 2: k1 tbl, k14, k3tog tbl, k14, wyif sl1p
Row 3: with col 2, k2tog tbl, k12, k3tog tbl, k13, wyif sl1p
Row 4: k2tog tbl, p11, p3tog, p11, sl1
Row 5: with col 1, k2tog tbl, k to last stitch, wyif sl1p
Row 6: k2tog tbl, k9, k3tog tbl, k9, wyif sl1p
Row 7: with col 2, k2tog tbl, k7, k3tog tbl, k8, wyif sl1p
Row 8: k2tog tbl, p6, p3tog, p6, sl last stitch
Row 9: repeat Row 5
Row 10: k2tog tbl, k4, k3tog tbl, k4, wyif sl1p
Row 11: with col 2, k2tog tbl, k2, k3tog tbl, k3, wyif sl1p
Row 12: k2tog tbl, p1, p3tog, p1, sl last stitch
Row 13: k2tog tbl, k2, wyif sl1p
Row 14: k2tog tbl, k2tog tbl, pass st over, cut yarn and pull through loop

Joining Triangles:  

To join modular triangles, you will cast on and/or pick up stitches from an existing triangle. Always work from the right side and always work from right to left. When picking up stitches, go under two threads of edge stitch. 

Pick up 17 stitches along the left side of triangle #1, cast on 16 stitches. Follow the directions for the triangle starting with row 2. 

When you knit a unit of 6 joined triangles, on the last triangle you will pick up stitches from edges of two triangles.
