Last year at the thrift shop, we had a lady bring in MOST of her pansy collection (tote bag, paper supplies, jewelry, umbrella, plates, candles, Tiffany style lamps, and MORE) - they were redecorating and down-sizing. She kept "the best" pieces that she couldn't live without and decorated the guest room with them.
The hubby's Coke collection went into his office/study.
The living room, dining room, and kitchen were stripped of "collections" and the wallpaper & paint were redone.
I knew a lady who collected owls when I was in high school - but she LIKED them. She had been a school teacher - something tells me owls were less obvious than APPLES............
Although I knew a school teacher (DD's kindergarten teacher) who collected apples - after retiring, she pared that collection down to the "best of the best" - and an apple sampler that I had cross stitched for her made the cut - she showed me a photo of the apple arrangement in one corner of their new house's livingroom.
Moving or redecorating does tend to give someone a good "reason" to get rid of an accumulation of things that they don't want to keep any more................whether they ever wanted them or not in the first place doesn't have to be mentioned. (Like the example by a previous poster of someone who hated owls getting saddled with a reputation as a "collector".)
