I bought these Jiulyning Invisible Ink and Black Light Combination Pens a while ago on Amazon. At $9.99 for 20 pieces, it was about the same price I would have paid for ready made Valentine’s Day cards for Grasshopper’s class. I modified a postcard style we used for last year’s cards and they are ready to be addressed by the boy himself! He hasn’t seen the pens yet and I can’t wait to see his reaction!
We do allow Grasshopper to have candy on occasion (and of course if his blood sugar is low he needs to have something with sugar to bring it back up) but we keep it limited. Even if we weren’t dealing with type 1 diabetes, on candy heavy holidays like Valentine’s Day, I still would appreciate some non-food Valentine’s in the mix.
More photos below and a short video show the project coming together. Happy Valentine’s Day!
