Ha...I may have posted a "stumper" of a challenge.
Whether you own stamps or not, you can stamp on layouts and cards! You can cut simple shapes out of potatos, foam core board, apply paint to a flower or leaf (yes...saw it in a magazine), or other objects like the end of a pencil, hands/fingers, feet/toes, etc.
I entered the paper crafting world through stamping, so I have a quite a few stamps and seem to collect them still (although I should use them more!). This layout came together really quickly with an alphabet set and 2 stamps from an arrow set. The background paper is Cosmo Cricket that Paper Pals sold some time ago. I "enhanced" the stamps with stickles to help them pop (have I mentioned that I love Stickles?).
