When you've got everything measured up and ready to go, it's time to glue your dowel down – we used liquid nails and a corking gun for this. Make sure you use slow and controlled movements when you're gluing – and don't go overboard with how much you use. Attach your first piece of dowel to the board and make sure it's flush to the edge so it's nice and straight. A good way to make sure it's straight is to nail that first piece of dowel to your board – that way it won't move as you're fixing the rest. A hammer and nails works well for this, but we used a brad gun as it was quicker and easier (make sure to use eye/ear protection when using this power tool – it's loud!).
Pro tip: Avoid nailing into the middle of your dowel – instead fix the nail on an angle between the one and two o'clock position.
