Re: Frames and higher plus lenses.

Preshape the frame. Most frames are built on a 6 base curve. Then trace or make your pattern.
If you're new at it, practice a lot.
Lenses will stay in under normal wear better, won't pop out if you have to do radical changes in pantoscopic curve. Don't be chicken to preshape a frame along the B meridian either. The greater your effort to match frame and lens, the better the crafts-ship!
There is no law against preshaping a frame. Ralph Lauren, Pierre, and the rest of the designers, I promise, will not sue you and you won't lose your license. Your patient will appreciate it, too.
