Thanks everyone for the replies! I did buy a garden kneeler (they were on
sale) and this is the one Paul James recommends. The way the legs are
formed are good for our soil (soil? did I say soil?, er, mean sand) down
here in Florida. Hoeing is not an option because of where the weeds are, so
hand-pulling is easier, on me!
