Evelyn chose to do My Little Pony cards with pink goodie bags for the girls and Teenage Mutant Ninja Turtle cards with navy goodie bags for the boys. With some assistance from me, she used the Horizontal Stripe Middy Bitty Bags in hot pink and navy to hold a Valentine's card, a bouncy ball, an eraser, and a couple of pieces of candy (though I didn't take pictures of the candy included).
On the outside, she used foam heart stickers to decorate the goodie bags, as well as heart-shaped gem stickers. We had to keep it a little less complicated because she was doing 22 of them, which included writing her own name on all the cards (not necessarily a fast exercise for someone still learning how to write).
Aside from the Whisker Graphics bitty bags, the Valentine's cards and heart-shaped gem stickers came from 99 Cents Only; the erasers and foam heart stickers came from Dollar Tree; the bouncy balls came from Fry's.
