tutorial: tailoring tank straps

A couple of years ago I bought this shirt that didn't hang right (waaay too low, as you can see) and was a little on the long side, but I loved the back (and still do). So I finally got off my lazy butt and decided to fix it (before and after photos, respectively):

Not sure why my legs are open in that first picture, to be honest. Anyway, this is the cool-looking back, pre-modification:

hey look! a wild bra band appeared!

Now, because I'm a) broke, b) cheap, and c) broke, I shortened the straps myself (obviously) and I'm here to share some diy-tailoring tips for tank top straps that are too long! The shirt I used in these pictures has a lace back, but this method honestly works with any kind of tank top (I've used it on thin spaghetti-style straps and tubular straps as well).
