Here are the valentines I made for our grandkids. I already posted the one we're giving to our granddaughter - these are for the boys.
I used the same die for each of them - cut out of different colors. The embossing folder I used for them is from Darice. The "Be My Valentine" stamp is from Inkadinkado. The "To my Special Valentine" stamp is from Darcie's.
Edited to add: The white border was done with a Martha Stewart punch. Thanks, M-J!
