I seem to be at my most creative during the fall! Nothing to share yet, as in nothing complete with photos, but I have planned for this year:
Turning a child's playhouse (one of those large outdoor plastic kinds) into a mausoleum or something otherwise creepy for a yard decoration.
Glass jar 'lanterns'. No real flame, but I'll do some with solid-colored paint and the shape of a leaf or pumpkin allowing a battery-powered light inside to shine through. Others will get the treatment I use on my solar fairy jars: thin glitter paint, a black silhouette such as a creepy cat or monster, and a solar light inside. All with handles, of course, so that I can hang them around my yard and light the place up at night!
A new monster for my yard haunt. My young sister has a swing on a tree branch positioned near the road on one side of our house. We found a $5 small decorative scarecrow. The body is just plain white and about the size of a small child, and can be removed from the stick. We'll dress 'her' up with raggedy clothes and a wig, maybe a mask or just a painted on face, then secure her to the swing with wire. Or maybe we'll forget the dress up aspect and just secure her then throw over an old white sheet for instant ghost child!
