I washed (and partly tumble dried) the red viscose (rayon) fabric as well as two other red knit pieces I found in the stash.
I'm going to use Simplicty 4076 from my pattern stash. It is from 2009 but I think still works.
I discovered previously that I don't like the flared sleeves so I will make them straight.
I will do one of the wrap front (the green below) and one with the gathered front (the pale pink below). The knot front is very low, so if I do decide to do that one I will add a faux cami panel into the front if/when I sew it.
