These Convention Samples use the stamp set Best Friends Forever from page 90 of the 2011-2012 Stampin' Up! Idea Book & Catalog. Since I hadn't seen the catalog prior to stamping my samples, I had no idea this set was in the 'Growing Up' section of the book. I think the set lends itself to more elegant cards and such also and so that's pretty much how I used it :) If you have any questions, comment or email me.
Have a great day!
