Waste not, want not, for real!
There are so many times that I recall some odd bit that I've tossed only to wish so much that I could still get my hands on it.
We live in an old house with limited closet space so I do try to curate my finds but Halloween is the one holiday that I'll save everything for. If I dig something out of my yard or garden I'll even save roots for repurposing. I let the nuisance vines run wild through September and October knowing they'll look great on my Halloween monster yardman once I rip them out and let them wilt.
Mr. B thinks I'm crazy but he indulges me. He loves Halloween as much as I do.
