Foam spider cutouts (mine are from Dollarama)
single hole punch (already had)
orange string/twine/ribbon (again, from Dollarama)
Punch holes in legs of foam spider (so it lays flat on the string)
String spiders along, well, string in an order you like.
Hang at mantle to take picture & fold up to bring out within the next two weeks!!!
This was *sooooooooooooooooo* easy that it would be a great craft for the kids to join in on too!
