I guess it’s too late to be doing a Halloween craft post, but this is something we tried today (Halloween day) afternoon. If you do not wish to do a pumpkin, the mosaic pattern can work with any other shape or theme.
Looking for a Halloween craft activity? Here is something I did with my 4 year old – we got our craft box out and made these spooky spiders for Halloween. All the materials are easily available at any craft store and I helped him do the gluing tasks.
