Knit your own Triangles within Triangles Shawl using these clearly-written instructions by knitwear designer Jackie E-S of HeartStrings FiberArts.
Triangles within Triangles Shawl is a simple, yet sophisticated, triangular shawl that starts with just a few stitches at the center neckline, and increases in pattern.
Since the knitting is stockinette stitch-based, this design uses a rate of increase that is slightly more than the typical "every other row" rate so that the resulting shape retains a pleasing width-to-length ratio.
The lacy and solid triangle motifs are set within the larger shawl triangle panels. A coordinating edging is used to bind off, as well as create a pretty triangle-shaped finish to the outer edge of the shawl.
For a 36" deep by 72" wide shawl in fingering weight yarn, plan for approximately 1200 yards at 4½ stitches/inch over pattern on size US 7 / 4.5 mm suggested. Model above shown in Haneke fingering-weight alpaca, color melange lilac. Easily adjusts to other sizes by knitting to length desired, and other weights of yarn with corresponding adjustment in needle size and yardage.
