I have stained a desk top and where the stain crosses over the slightly earlier application there is a dark mark. There's no finish on top of the stain. The wood was prepared properly for the stain but when the stain was applied across the large surface when you go from one area to the next there's a crossover and that created a dark area or darker stain.
Should I take it all back down to the bare wood and start again or can I re-stain it trying to make the entire surface dark? Your thoughts?
