So I cut off the sleeves and took it in. And then I cleaned the mirror. I was going to blame the bad pictures on the fact that it's a really old mirror and has some spots, but I didn't think I could pass off fingerprints as "age spots."
Ah, much better! The shirt, I mean. I guess that's about as good as the mirror gets. (And do I always look that white? I'm going to have to blame that on the mirror/lighting as well.)
My sewing machine didn't totally freak out this time when I tried to sew a knit fabric (yay!). I just took it pretty slow. What can you save from your Goodwill pile??
