I got in on my first try!
I actually got in 2 issues of Take Ten and 1 issue of Stamper's Sampler with just that one set of cards I sent, so don't rule yourself out just because it's the first time you've sent something in!!
I found out the first time because someone called me and told me I had 2 cards in that issue. I didn't know a thng about it! So I called Somerset Studios and they made sure I got my free issue. At $15.00 a pop I was going to make sure I got my free one!!
So don't give up yet!! Sometimes they won't use things for a few issues. My Stamper's Sampler one was months later!
Happy stampin!
