I am thinking of putting in a run of shaker peg rail on one wall in our little mud room/hallway.

For the 'rail' I'm thinking of using 1/2" white pine - or maybe poplar as it's generally easier for me to get in decent shape. Good choice? I'm also thinking of running a bead along the top and bottom. Thoughts?

also, any recommendations for a source for the pegs? I'm assuming they need to be longer than most drawer pulls I'm likely to find in most places.
