I agree that The Costume Goddess is a good place to start. Tribe's unfortunate tendency to include punctuation in URLS will trip you up if you try to use the link above, however; try
www.shira.net/cg/coverbra.htm
and
www.youtube.com/user/Xanadance
to get the benefit of Fatima's advice.

At this point I am guessing that the 'pockets' occurred because you tried making a pattern for the cup covering instead of draping it on. For your first bra I really think the draping technique, as outlined in Dina/Costume Goddess instructions, is the way to go. Use lots of pins and be patient with yourself. It will suddenly 'click' and then you'll be covering bras and whistling while you work. Also - you can drape the entire cup with one piece of fabric if you want to - dividing the drape into two parts (top and bottom) does give guidelines when the time comes to add coins or fringe etc but if you dart the fabric as you drape it is not necessary... well, I'll say not necessary if no larger than a D cup. I've never covered larger than that, maybe the rules change.

I totally forgot Misha's tutorial!!! It's really good (actually all her tutorials are). That's pretty much what the CG suggests and what I do.

Thanks, Bellatrix, for the costume turorial tribe. I immediately joined...
