I am thinking of making my own underwires...from wire jewelery making I know that lightly hammering on wire causes it to stiffen...so if I shape the wire as desired and then hammer on it to cause it to take that shape permanently...I should have underwires..why do this? I live in the boonies..do not yet know the size of wires I need and the mail order business that sells the supplies...charges almost $20.00 for shipping. wondering how long it will take the wires to rust...

I was able to add 2 inches to my band size by going to a gym and working out with weights...then I had a size that was commonly available...a 34 instead of a 32..and I saved money too. You need to ask a trainer for the specific exercise. If its a small gym with a trainer owner you, like me, might get the information for free.

It would be nice to know from the author, which method of measuring for band size is the correct one..as another method has been suggested.
