Wood filler for different shades of walnut
I posted earlier about the herringbone table I'm working on and now I'm curious on people's thoughts regarding filling the cracks. There are going to be some gaps between pieces of the wood because getting them perfectly the same was impossible. So, as you can see in the picture, there are lots of different colors, shades, etc. in the wood and will be plenty of little crevices to fill. What would you guys do for filling? I've considered the following:
Use a walnut filler like famowood everywhere and just go with it. Won't match all the grains, but maybe that's ok.
Make a slurry out of sawdust from the walnut and my sealer/finish (I'm using Waterlox), and rub it into the cracks/grain.
Wet sanding with the finish and 320 grit sand paper to fill in the grain. Would that produce enough for the little gaps as well.
Any other thoughts on this? Should I do the final sanding down first before filling or fill and then sand down?
Lots of questions, I know. Thanks for your input!
