I gave each of my kids a black sheet of construction paper and a bottle of glue. Ben (2) went to town with the glue. Squeezing it out on the paper is his favorite part of arts and crafts time so I just let him do his own thing. Molly (5) requested a pattern to go off of, so I drew a large spider web on her paper using a white crayon. She traced it with glue and then sprinkled it with ... GLITTER!
My two-year-old did a great job of NOT making a mess with the glitter - I couldn't be more proud. (Just had to put that out there!) When their spiderwebs were complete, we added on a paper spider. Molly made a glitter face on hers which was cute. I used my Cricut electric cutting machine to quickly cut out a couple spiders for us, but you can totally just make your own. Maybe with cotton balls? If you wanted to make the same shape we had, use the Mini Monsters cartridge!
