I think this question was asked last month, but I can't find the thread. I am trying to generally match existing 100 year old knotty pine with new stock. The old stuff has that yellow hue with which you are all familiar.
I was going to get a test board and seal both sides with shellac. Then try different methods for each section of the board. Adding various hues of Transtint dyes to a second layer of shellac and using a gel stain. Top coat all sections with polly and pick the best match.
Does this sound like the correct plan?
