I took the Sewing with knits craftsy class by Meg McElwee from Sew liberated a while back, and I highly recommend it if you are feeling a bit hesitant about sewing in knits.

I made this tee from the class material in rayon fabric, problem nr 1, rayon growes, nr 2 it has no body, nr 3 the scoupe neck is lets say very scopy, result is not so flattering, and this tee will probobly end up as sleepwear.
