In only a few simple steps they can be yours too!
1) print the valentine cards on thick card stock & cut them out. (link to FREE printable: here)
2) have your little valentine write their name on the cards
3) wrap washi tape around the middle of the bubble bottles (washi tape from Michaels craft store $4 for 2 rolls & bubbles from Dollar Tree $1 for a pack of 6)
4) punch 2 holes in the corner of the card
5) use craft string to tie bubbles to cards.
TA-DA! It's that easy.
