Found this on eBay, already sold.
Found on Etsy.
First one I noticed was this blue cup and saucer.
Then a yellow one, both from the same Etsy shop. Prices for these vary online. But, I decided not to buy. Too much when shipping doubles the cost.
Paragon Tea Cup and Saucer with Canada Coat of Arms from Etsy.
Found on Pinterest then Instagram (seems to be the source).
This is one way to repurpose old teacups, especially those which have lost their saucers. It would take a little bravery to glue them together and hang them all up. Depending on the quality of your glue it could all end in tears and broken china.
This was on Pinterest, no original source.
