Speedy Racerback Bralette Yardage

Indigo Guinea Fiber Sparrow Fingering  1, 2, 2, (2, 2, 2) {2, 2, 3} skeins (460 yards / 421 meters per 100 g), 75% Superwash Merino, 25% Nylon. Held Double.

OR 456, 503, 580, (635, 683, 750) {798, 874, 927} yards / 399, 442, 509, (555, 599, 655) {697, 765, 809} meters of fingering weight yarn held double, or half that for DK weight yarn held single.

Choose a yarn that you will find comfortable next to skin. A soft yarn with stretch and memory is ideal. 

Out of all my samples, the most supportive one is the one knit with Hikoo Cobasi (50% cotton, 21% elastic nylon, 16% Rayon from Bamboo, 8% Silk) held double (Dark grey sample). The elastic content and density of the fabric really helps with support.

For more support, choose a slightly plumper yarn worked at the same gauge to get an even denser fabric.
