Here are the gumball valentines that I designed. I think they turned out really cute. Hope you like them! Here is the tutorial and free printable, so you can make them too!
Get the PDF to print the bottom part of the valentine here.
You can print it on any color paper card stock that you wish.
I used fold top sandwich bags for the gum balls,
but you can also use plastic wrap or other small clear baggies.
