My son picked out these little glow-in-the-dark aliens to give out as valentines. His preschool specifically asked not for candy or treats so we headed to Party City and this is what he found.
I created a background and printed them on card stock.
He attached each alien with glue dots and then signed his name.
We packaged them up in clear envelopes from ClearBags. Check them out for any paper, envelope, packaging and cellophane needs. All sizes and colors. Seriously. I have stacks of colored envelopes in many sizes sitting around for projects just like this one. I like the envelopes because they are flat and are self sealing.
