i like to work a small area at a time. because i am so picky about alignment, i tend to be slow. by working a small area, i have plenty of time to lay the pieces and then adust them... and adjust them again... before the glue sets too much.

with the caulk gun, i dispense some glue in the area, and then just a small palette knife to spread the glue as evenly as i can throughout the area.
