2 Goggly eyes
I cut a piece of contact paper and taped it to a window, sticky side out.
Next I handed D the child scissors and yarn and let him cut away - his current favorite activity. He stuck the pieces of yarn to the contact paper. (I did guide him for the first 2 but then he got the idea).
While D was busy cutting and sticking I cut out a spider shape out of the black paper. Then I had D glue on the goggly eyes. When he was done with cutting and sticking I gave him the spider to stick to the web.
He was so pleased with himself and its looking pretty spooky round here!
