Homemade 3-D Valentine's Card

For several years I've been participating in Valentine card exchanges with Christian homeschool moms from an online forum.  It's a lot of fun sending and receiving cards for my favorite holiday.  Reminds me of the card exchanges we did in public school when I was a kid.  Anyway, I had to take a picture and post about one of the cards.  This gal makes her own, and I was very impressed!  It arrived flat for traveling through the mail, but it opened up to form a little box with hearts and mail popping out.  So adorable!
