Oak larders or doors are the best "cheap" ways. The only other way that is cheaper is making cape stands or something, but the xp/hr is -extremely- slower.
Dungeon doors/Oak larders/Limestone fireplaces are about all I can think of.
I guess you could do like normal chairs or tables or something but would take a long time...
Personally I did Mahogany Tables with Scared Clay hammers.
