This is coming along nicely. The pattern produced some interesting challenges. Intarsia in the round is not a challenge but getting the width of the horizontal red to match the width of the vertical red was. I tried Latvian braid but it was excessively fussy for the desired result. The answer proved to be a sizer larger crochet hook and surface crochet worked in the desired location. The second challenge was getting good corners where the red changed directions.
I’m having to cut the background color’s yarn at the start of each square. It’s not onerous and the result is very good. I’ve been working in ends as I go.
