Muscle Tank Test


An easy-going sleeveless t-shirt is comfortable to wear
and looks great with a dressy skirt or with casual jeans.

I'm looking for testers for my Muscle Tank in fingering merino. Use a single color of speckled or solid yarn, make a fade, stripe it up with two colors, or go wild with random stripes of fingering yarn from your stash. Any fingering weight merino will do.

Worked bottom up in the round to armholes, then split to work the chest flat. Join the shoulders with my favorite seam, the 3-Needle Bind off. The stockinette body is accented by a seed stitch bottom border and crocheted finishing around the armholes and neckline.

-2” ease intended /  Finished bust size 28” (32”, 36”, 42”, 48”, 54”)
