this bra idear is suuuweeeet!
i may have to try this....and the undies. yours are super cute. love the green (my fave color!)!
Mine too!! You know, if you couldn't already tell that from the walls, undies, and belly button ring...
Anyways, the seam allowance was just the normal 1/4". I used a knit shirt.. I think. It was just a plain Hanes kinda one.
It make an underwear set out of one t-shirt, I always cut up the sides and sleeves first so that I have one big piece of fabric. I can fit all of the bra pieces on the front, the front and back of the undies on the back, and the 2 crotch pieces from the sleeves.
Hope that helps!!
