A secret quilting Angel is kept a secret.
Quilting Angel knows you and you know her/him.
Secret pal swap is kept a secret until the package is delivered with a note of who it is from. There is a secret pal swap on the board that runs from month to month and you have a different pal each month that you sign up.
I don't know how you would become a secret Angel.
I have a wonderful Quilting Angel who contacted me first so as not to insult me by just sending something. I would never be insulted by a surprise package. Anyway we have become great friends and everyonce in a while she sends me quilting things in the mail. I can't tell you how excited I get.
I have also sent items to others who needed help.
If you really pay attention to some posts you will be able to find someone to bless.
