Bill,

I used leather for a hall tree cushion, and I call some upolstry
shops and found one that did leather upolstry. They had whole hides
in a ton of colors, and was able to get a few square feet. It ain't
free! Wives who sew are a great source of info in making cushions,
they say it's not hard with a sewing machine. Goodwill, St Vintys,
or a thrift store might be a good source for a "test" cushion to get a
pattern, and see construction details.

Hope this helps.....
