I sewed a plain white t-shirt some years ago, but then I found it too plain, so here’s another boring white t-shirt upcycling. I refashioned the white t-shirt into a nautical top: I added blue t-shirt fabric stripes and a sailor collar at the front.
I cut up an old blue leggings which was full of holes. Then I appliqued stripes with zig zag stitches.
I also added a faux sailor collar at the front using leftover white knit fabric from an old t-shirt.
