Since Wilder only has 7 other pupils in his class, I knew we could go with semi-homemade Valentines this year (guys, I'm sooo tired!).
I found some cute Love Bug Valentines on Dandee, A Happily Crafted Life, and was pretty tickled she even included a printable of the mason jar.
We just taped our critters down but the original tutorial uses some kind of invisible adhesive.
I spent probably $3 and 15 minutes total on these and know they'll be a hit!
