Silver cake baskets are a new discovery for me. I love all sorts of silver patterns and objects so pretty and so useful. Cake baskets became popular in late 1600''s through the Victorian era and some even into 20th century. I tend to like the ornate rococo style. I can think of many uses for a cake basket on a tea table beside holding cake.
They would work for small floral arrangements, to hold cards, small ones could perhaps hold candy.
Being a Southerner I find it hard to resist silver objects for the table.
Have a Pink day!
