Have you ever sent your cards in to be published into a stamping magazine? I send mine to Just Cards Publications. You can see the address here. What I do is this: Send them in no less than 10 at a time. Write on the back of each one your name, email address, city, and phone number (I blurred my phone number out in the 2nd photo). Then, write the directions what you used and how you created the card. Lots of stamp companies will give you free stamps, free store credit, etc. if YOU let them know if you do get published. For example, if this card gets published I would contact Unity Stamp Company and they would let me pick out $25 of FREE PRODUCT. It's great!!!
I posted this card yesterday but wanted to tell you what I do to get published. I send cards all year long. You never know when they will pick one of your cards to be printed that month. And I just think you have a better shot at getting published the more you send. You also get a free magazine from Just Cards so its a win-win for everybody!!
