Today I purchased this vintage oak drop leaf table, very inexpensively at a local used furniture shop.
(The picture is taken in the shop, not my house).
This allows the former dining room to remain as my study, and releases the old study/sewing room to be almost completely for sewing! I may put the folding guest bed in the sewing room too. Making really good use of the whole house whether it is just for me, or when guests have come.
The pieces are rather a mix of styles, which is a tiny bit jarring, but I shall manage because its practical.
