Most often materials begin the process.
I like to say I’ll go to the studio to rub two sticks together to see what comes out.
I keep an assortment of wooden elements around in places immediately visible or catalogued in my mind while in a drawer or the basement.
In the present age of recycling, salvage facilities are a good source.
Curbside finds are exciting because their locale is part of their story.
Much good wood is thrown away.
Quite broken, non repairable furniture is desirable.
Old, very seasoned interior plywood is often better than can be bought new.
Found is always better than purchased. Not spending much is part of the ethic.
Furniture styles are laden with associations.
Generic qualities are desirable.
Reproduction or contemporary furniture since the 1970’s is for me unusable.
Never use particle board. (Though, I can imagine a work about particle board.)

So far I’ve not used laminates, though their colors and patterns are specific to their decades, thus associational.
Tile is very compatible with wood, but may compete if patterned or too colored or glossy.
Have not explored mosaic. Tile is also specific to decades.
