I think I have the overlocking bit down for knit fabrics but when I went to over stitch using my walking foot, I managed to completely ruin the neckline on both.
The black, white and grey fabric is from Fabric a brac. I really liked it but unfortunately don't have enough extra.
This is merino and I think from Fabric Warehouse but I"m not sure. Its very stretchy. So I've signed up for the Dreamstress' Basic T course at Made Marion and the Ultimate T-Shirt course on craftsy. I really want to get my head around knits this year.
