A fabulous custom made cabinet for displaying a fine 18th Century Porcelain service. In Europe at this time, hand painted porcelain from the Far East was highly prized and sought after as only Japan and China had the secret recipe for hard paste porcelain that was so resilient to temperature. The table ware sets were often made to order with the family coat of arms. The fascination for all things Japanese and Chinese has endured through the centuries and continues to this day.
I have a bunch of fancy teacups and I use them for everything except tea. They're perfect for yogurt, especially if you have demitasse spoons. I'll eat harvest crunch out of my Royal Albert sugar bowl. Or make my magnesium supplement drink in a teacup. Or use my teacup saucers for pretzels.
I use teacups and saucers on my bathroom counter. Royal Albert saucer under the hand soap bottle, because the cup broke a bajillion years ago, and it looks pretty. Milk pot to hold my reusable makeup wipes. Teacup for hairsticks and eyeshadow.
Old mugs for holding pens, saucers for under the African Violets, and platters for the bigger plants. More saucers for holding my pins and embroidery scissors and thread.
Fine china can be used for whatever. Stop looking at fine china like it's grandma's precious heirloom, and start looking at it for what it is: organisational vessels. Pretty things to hold stuff.
