Stretchy Knit Bandeau

Bandea, tube top
I had it in my head to see about making a bandeau for part of my costume. Again, having NO idea what I'm doing, I just measured around my chest, folded a piece of spandex or stretchy material in half, cut, pinned like a mad man, and (dun dun duuun for the first time ever) sat at my sewing machine, read the manual, and had at it. The most aggravating part was threading the elastic bands through...

Granted, this thing is FULL of flaws. Oh my god. None of which you can see (I'll be the only one to ever know...). I've already got a design change in mind for the next one...

Hopefully the next one will look a tad bit more professional. LOL!
