twenty bucks at a garage sale bought me an older pine table for my dining room. i have the top sanded down with 80 grit. what next? i know i want some sort of natural, non-painted surface. my main concerns, in order of importance, are: durability / low or no maintenance / appearance. keep in mind i have no special knowledge or tools...and want to keep this project on a low (lowe's) budget. thanks y'all!
