STACKED TRIANGLES knitting pattern
This pattern was originally published in 2019 as “Triangles II”, block #10 of the original “52 Square Pickup” KAL. It has been fully updated for 2026 with a new high-resolution chart, revised instructions and project summary.
Build stunning architectural texture with the Stacked Triangles block. A standout piece in our Textures & Geometric Collection, this design uses simple knit and purl shifts to create a rhythmic, interlocking triangular motif. I’ve updated this pattern to with a high-contrast chart to help you track those 16-row repeats with ease. It’s a sophisticated choice for a modern nursery blanket or a high-texture kitchen set.

The Pattern: General Instructions
- Cast on sts
CO 43 sts with US 7 (4.5 mm) needles.
I always cast on and bind off stitches with larger needles than I use for the main work. This prevents my cast on and bind off rows from being too tight. - Garter stitch bottom border
With US 6 (4 mm) needles, knit 4 rows.
Slip first stitch on every row as if you were to knit it, but without knitting it (except on the first row). It will form a neat and sturdy border. - Main pattern with garter stitch side borders
Continue working the next 55 rows as follows:
4 garter sts, Stacked Triangles knitting pattern over 35 sts, 4 garter sts
Note: Work the entire 16-row pattern 3 times complete, and then rows 1) to 7) again.
You can follow either the row-by-row written instructions or the chart below for the Stacked Triangles knitting pattern. - Garter stitch top border
Knit 4 rows.
- Bind off
Bind off all sts with a US 7 (4.5 mm) needle. Cut yarn and weave in ends.
- (Optional) Blocking
Block your square to its final measures.

Stacked Triangles Block: Chart
- Read all odd rows from right to left, and all even rows from left to right.
💡Note & Tip: These charted instructions represent the 35-stitch design area. Remember to work your 4-stitch garter borders at the beginning and end of every row. I recommend using stitch markers to separate the borders from the main design area.
