All manner of things
...books, skulls (not real ones), good crystal, vases, anything vintage and unusual, obsessed about chairs and furniture but am kept in check by my husband
, mirrors, art, anything that can be put on the wall. Outside....plants, plants and plants, and pots, plus any overflow from the house that will withstand the weather and look "sculptural" (well to me anyway). Only the amount of pets the law allows ....otherwise I'd have a petting zoo
. There's probably more, but that's all I can think of just now.
