I've been doing all sorts of things to get ready for our granddaughter coming to spend Christmas with us. The latest was to dig out the old wooden high chair and give it a make over.
As for the chair, I cleaned it carefully, washed the fabric retainer belt, and put wood cover up oil on the blemishes. The tray was more of a challenge. It took two coats of stripper to remove the rest of the old finish, then Gary sanded it with three levels of sandpaper, then I oiled it with mineral oil as you would a wooden cutting board.
It doesn't look perfect, but it isn't too bad, and of course, baby looks cute as ever in it.
