Hi!
Save it to submit to them.
Watch the magazine's calls and to find one to submit it to one it's applicable for. Paper Crafts (who does Stamp It!) often posts them on their blog (
www.papercraftsmag.com/blog).
I just completed a term on their editorial board. Believe me, the magazine editors love to see cool stuff and are always looking for new talent to feature.
Good luck!
