Won't you be my Valen-slime? These cards are perfect for your slime loving munchkins. Just print on cardstock, cut out and attach slime. I found my slime at Target. They are called heart putty. They come in a pack of 16 for just a few bucks! These come in pink, green, blue, and red. I have included two different card sayings, "Will you be my Valen-slime?" and "Happy Valen-slimes Day!"
