Chomp's was my favorite valentine. I had left over test tubes a previous party. So, we made a mad lib for each child and rolled it up with a golf pencil, corked the entire thing and added a tag with bakers twine. I love when I have all the supplies needed for a project.
Last was KF... her pick was seed packets. We found them 4 for $1.00 at the dollar store and stocked up. From that we created a construction paper pot that opened up and added a "heart" flower.
Ever since my kids were little we made our Valentines. Sometime I wish I could just go pick up a box of cards and be done, but I am always so proud of what we create.
