Basic Skills Necessary:

  • Cast on
  • knit
  • purl

Pattern Description:

Pattern is both charted and written - with US and Metric equivalents.

Beginner skill level - knit, purl, slip only.

Very versatile wear - fully reversible, with a unique shape.

Easy and fast to knit up with only 180yds of super bulky yarn as shown!

Play with gauge.. Looks great with DK on US 6 (4mm) or with superduper bulky on US 35 (19mm).

This is an interesting stitch pattern of alternating -2 row /5 st 'bars of knits then purls moving zigzag fashion across a base design of K1 P1 ribbing. The movement of the bars across causes a slight scalloping at the lengthwise edges, which I have accentuated with a 'hard' or 'shaping' block finish.

Pattern name comes from the look of the arced edges and the triangle look to zigzagging 'bars' reminding me of the method of using arc drawn with a compass to figure the angles for a right triangle from just the hypotenuese. SCARY GEEKY I know!
