I collect antique/vintage china with roses or similar flowers on it, especially cups and mugs with ornate handles, creamers or small pitchers, and plates.
I also collect vintage reproduction tin signs, usually with flowers, cats, angels, fairies, valentines, or Parisian scenes on them. Some are old advertisements for seed companies or feed. I also like tin boxes that are similar.
I have a collection of porcelain figurines of cats, angels, etc. but I rarely add anything to it. It's mostly things I got as presents growing up.
I also collect vintage or vintage-inspired linens, mainly chenille bedspreads, quilts, and handkerchiefs. I am running out of space to store linens so really have to stop, or get rid of some.
I guess I could also say that I collect armoires. I don't have much closet space in my house so really need them for storage. I don't think I've ever met an armoire I didn't like. lol
I have quite a few things from the shabby chic line at Target, but I missed getting the large armoire they had several years back that had glass doors on it. I still kick myself for not getting one.
I suppose I also collect wall hooks because I have them all over the place. Also really like old crates, baskets, metal buckets, wire baskets, or ornate metal shelves.
Oh yeah and milk glass...vases especially, since they are common to find in thrift stores. Also quite a few milk glass lamps.
And glass bottles, especially colored ones. I put them in my windows, or else use them in the garden for flower bed borders.
