I am hoping against hope someday to make a doll house. My scale is 1 inch to 1 foot. Today, I was cleaning and found this pillow of air for shipping. It looked so much like a pillow, I just had to share an idea.
If your doll house plans do not include things being played with, you can cover this with fabric or lace and no one would know it's not a real pillow. And if something happens that as you're sewing it, you pop it, you can simply make a slit in it and stuff it or just stuff the new fabric pillow with batting, old nylons, plastic bags, or tissue paper. It's 2.5 by 5 inches and perfect for a twin or double bed.
If you are doing a miniature house in one inch scale, your pillow will be too big for your bed. It's a great idea, though.
A standard pillow is about 18X30 inches, so your miniature pillow should be about 1.5 by 2.25 or 2.5 inches, so maybe you could cut the packing pillow in half and stuff it with something. Then you could cover it and it would be awesome.
