I used Lion Brand Wool Ease. It is pretty much skintight because I messed up the gauge. I did a gauge swatch knit back and forth, not realizing that my gauge when knitting in the round is a lot tighter. Oops. But I think it looks okay anyway. Not perfect by any means, but not bad for a first wearable.
Also I had trouble figuring out the straps. The pattern had them knit with the ribbing border but with reverse stockinette in the center. I thought they looked better the other way around. I couldn’t see a close enough shot of anyone else’s to tell if they did it the way the pattern recommended or reversed it. :shrug:
