Drilling holes will let the nylon line stay at one place. Otherwise, cut or saw notches at the sides for the same purpose.
These Ikea wood are softwood. Holes can easily be drilled using a electric drill.
By the way, a portable electric drill is very handly to have around the house. It can also be used as a powered screw-driver. Turning screws manually can be tiring on the muscles after a while.
