When the boys were younger we would often play "I Spy" when we were in situations where we had to pass some time. So when I came across these magnifying glasses at our local shop I thought they would be perfect for non-sweet valentines.
The I Spy Valentine Cards fit the mini magnifying glasses. All you need to do is print out the card and use a piece of washi tape to adhere it to the card. For the regular size magnifying glasses I designed little I Spy Valentine Gift Tags that you can tie onto the magnifying glass handle with a piece of ribbon. Check out your local party supply store for magnifying glasses in the party favor section or you can also use mini binoculars.
