To recreate your Valentine's Day cactus cards, simply add three green "thumbprints" on a piece of white cardstock, on top of each other in a "Y" shape, just like you would see a cactus in real life. Repeat this step about two to three times on your card front. You don't want to over-crowd your paper though.
Follow that up by drawing on cactus small features with thin-tip markers {like black spikes, brown pots and pink flowers!} to make it come to life.
And that's it! Your card is finish!
You could also add on a few sayings like "stuck on you" or "so glad to be stuck with you" to tie the theme together.
Then mail and/or hand-deliver your thumbprint cactus card to the lucky receiver!
