nervous about finishing T/oak
Hi, I'm a bit nervous about finishing some Tasmanian Oak shelves that I had cut for adjustable shelving. I was thinking I'd like it a walnut sort of mid brown, cool based rather than golden and fairly flat or satin but I haven't stained anything before so I'm worried that I'm going to use the wrong thing and just ruin the timber. I have gone over the cut ends of the shelves with a sander but its not super smooth like the dressed (?) edges so I'm not sure if I should use a primer first.
Maybe as a complete amateur I would be best not worrying about colour but just oiling the timber? It's in a wardrobe so is there a minimum step I could take to protect the timber?
Thanks in advance for your advice!
