hanging a shelf/cabinet

[Medusa]

i'm planning on hanging a 20# wooden shelf to store my spices closer to the stove. i am trying to find the sturdiest way to mount them. i"m planning locating the studs and drilling pilot holes, then mounting the 6 shelf unit with 3-4 inch screws into the studs. is this the best/most durable way to hang them? thanks for any advice

Just one and don't hate me for this: it's best to not store your herbs and spices too close to the stove. A cool, dry place is better. It may be more convenient near the stove but the heat and humidity lessens the herb/spices potency. As for hanging the shelf, I'm worthless in that dept., sorry.
