Yea. thanks for the response. I haven't been on Photoshop today yet to play around with it . I'm new at it,( Obviously!).
But I guess my dumb question was if you could create the mask in design to paint the layer below. Like masking windows on a real car before painting. I saw Matt Kohr do it. But, maybe that was a "quick mask"?
I hate the marching ants too . LOL . And also I've been loading selections, which i thought was cool when I stumbled over that capability.
But when i'm making numerous strokes within a selection I end up with the wonderful ugly jagged edge which defeats the whole idea .
as you said you are using photoshop ,can you specify the version ??
This is the help link of refine edge for refining your jagged edges.
