I've been making candle holders and business card holders out of pine and white wood. I have obviously been staining the pieces with a oil based stain and the after about 24 hours I apply my first coat of semi gloss poly, then sand with 220 and apply my second coat, then I sand with 320 and apply a third coat. After the third coat is dry I finish everything off with a 600gr wet sand with a little lemon oil. I've been having problems with the corners and edges of the pieces when I sand after the first and second coats. A lot of times the stain gets taken off or messed up. The best thing I've ever stumbled across was the finishing wet sand because it does not take the stain off and doesn't make the ends looks dusty or cloudy. My question is should I just wet sand the entire process since the wet sanding at the end preserves the stain? Would the wet sand cause problems for the coats of poly or would it be ok? Here is a pic of the problem I'm having. You can see where the stain got sanded off even with a very light sanding but you can also see how nice the rest of the piece turned out after the wet sanding at the end.
