Trimming Out the Edges Between Molding and the Floor?

You need to go to Lowe's to find what you need, good luck.

The easiest solution is to go get strips of quarter round molding. Put it against the floor and the baseboard. It will extend the baseboard with a nice finish and can be easily caulked and sealed. You might want to paint it the same color as the baseboard before you attach it to save yourself some trouble keeping paint off the floor.
