My 10-year-old son and I have been building a desk for him. It is his first woodworking project. We built it with Southern Yellow Pine and joined it using pocket holes with wood glue. We also had portions of the desktop that we used stainable wood filler. It was sanded down to #220 grit (#60, #120, #180, #220) using an orbital sander. Minwax Oil Stain recommended sanding to #220,. Last night we vacuumed the desk then wiped it down with a damp cloth. After it had dried we stained it with Minwax Ipswich Pine 221 oil stain using clean cloths. We did not use a wood conditioner. Unfortunately, the first coat of stain is much lighter than expected. We would like it to be darker. I am concerned that it was over sanded. What should be our next step (add a different stain darker color, sand off the first coat and start over, sand between coats, etc.)?
We plan to finish with 3-4 coats of Polyurethane and Finishing Wax after drying. Thanks for any advice you can offer. I have attached a couple of pictures pre-stain and post-stain (first coat).
