First trim down your white cardstock so it will fit on the front of your pre-made cardstock cards.
One piece for each card.
Once trimmed down, go ahead and glue those to the front of each card with your adhesive.
Repeat for each card you are making.
Now grab your kitchen sponge and scissors.
Cut out a triangle for your watermelon slice. It can be any size you like, just as long as it's not bigger than your card.
Now grab your paper plate and craft paint.
Squirt pink paint on the paper plate.
Take your newly made "stamp" and rub it into the pink paint, until it's completely covered.
Then take it and stamp it on the white cardstock.
Repeat for each card you are making.
Next grab the green and black craft paint.
Paint on the watermelon rim and seeds on the stamped design.
Set aside to let it dry completely.
To finish off the watermelon themed cards, add your scrapbook stickers/use Sharpie markers around the watermelon slice design to say "You are ONE IN A MELON" or any other saying you like.
