Hi Nicki; the shelves were made by drilling holes in solid wood shelves and running rope thru the holes (with knots tied under each hole). HTH! Also, since this was a reality show you can buy the episode on Amazon here: http://www.amazon.com/Casual-Cottage-Sunroom/dp/B00BOAJUSI The program shows the shelves being made by the host, Josh Temple, and the homeowner.

Hi Roger and Nicki - I remember that we also had to be sure each shelf was level and I think we might have also secured a shelf or shelves to the wall. Roger - do you recall that?
