I use my Mom's serger. I wish I had one...... I've tried it on a standard machine, which I do have, but it doesn't work as well. You have to stretch the fabric as you work and then it doesn't lay quite right when it's done.

I checked out Title 9 for sports bras. Didn't really see anything that grabbed my attention. I'll keep looking......... Haven't checked out the halter top yet, Veronica. Will do so. Thanks for the suggestions, ladies!
