What a clever idea. I had some Boyds Bear furniture that I sold on ebay one time. I'm kind of wishing I had kept some of it now but it probably wasn't really sturdy enough.
I also tried the samsclub.com site and didn't see anything for less than $150 that looked kind of like what I wanted.
I'm thinking maybe a doll bed. Little Bit is only 3 lbs so it wouldn't have to be too big.
