pegs eventually fall out of pegboard. I really hate the stuff.
I have a lot of shelves prelaminated and put up with 90 deg brackets. There must be 30 feet or more in the original 8x12 room which is now the wet room. Enlargers moved to separate adjoining room.
I would move the enlarger to one side and have a long table or cabinet space. A framing/print mounting space is useful.
Cabinets are better than open dust catchers.
I also could not change to work trays right to left. Too old to change.
I will never have a room without water and air filters.
