Maya-
I have only submitted at Simple Scrapbooks (SS) and Creating Keepsakes (CK). The websites are

http://creatingkeepsakes.com
http://simplescrapbooksmag.com

All the info about submitting is on their site.

I once heard (from someone on this list) to submit everything...although most people just submit their "best" stuff. Although you never know what they are looking for.

Good luck...and let us know if you get published!
