I don’t know what it is, but I love Lazy Susan’s. So practical! Picked up this solid wood extra large one the other day, added some upholstery tacks for interest and gave it a coat of ½ Old White and ½ Country Grey I had left over from another project. Two coats of wax for extra protection and it is ready to be put to use. How do you like it as a bar? They are also great on a desk to keep your ‘stuff’ tidy.
