Neckties: Silk, preferably. Found in used clothing stores. Check the tag should say 'silk', or anything else that catches your fancy. Cheap, less than a dollar, most $.25. Fabric is small, prints are lovely, some suitable for framing as prints or mini needlework. Rugs, drapes, upholstery, table cloths, bedspreads and throw pillows etc. It ravels easily after cutting, may have to stabalize with a light glue line. (Judie)
Aquariums: Small ones, often sold at yard sales for a couple of dollars. Make wonderful glass room boxes. Some plastic or acrilyc ones can be drilled for lights and wire. A tiny hole in wallpaper with light behind and fiber optic can lead light to a table lamp or use hole in paper and put a wall sconce over it. Larger Aquariums can be used for big houses. Silicon sealer makes nearly invisible but strong glue for floors and other attachments. (the same stuff the tank itself is assembled with) Big ones are HEAVY.(Judie)
Fullsize trees, the ones that tower over the house: Yucca skeltons, you find them in the west every late fall. They are wonderfully shaped and can be embelished with folage. Glorious shapes and texture. Had for the taking everywhere. Look around any southern/western neighborhood or countryside. (Judie)
Beads, baubles, shiny stuff: Yard sales, used clothing stores. Fancy tops and embroidered clothing. Stains are ok because you only want the beads and stuff. Beads are expensive. Might check for silk blouses too. Wonderful stuff, silk. Flows like water and make gorgeous accessories. Old t-shirts, the ones that have been washed a thousand times. Great fabric for minis, drapes wonderfully. (Judie)
Coat hangers: The ones from drycleaners, thin. Curtain rods, golf clubs, ski poles, curl them with needle nose and gild, flower stands, plant hangers, anything that comes to mind. (Judie)
Take a walk in the country, or around your own neighborhood: Fall is wonderful because it drops it's clothing and lets it's bare bones show. Those bones are amazingly useful and delightful for the mini person to use in a thousand ways. Take a few plastic bags where ever you go.(Judie)
If you have access to a band saw: Buy a piece of 1/2 inch thick oak trim about 5" wide by 18" long at a home center. Using a band-saw, slice it into the thinest strips you can consistantly cut.
