Hello all, I was wondering if anyone can recommend some great sources for wood grains? I currently use polligon but looking for some others? I design furniture and want to explore more options for wood grains and high quality ones! 
Thank you!!

Arroway still have some of the best - mostly for how comprehensive and well organised the library is.
Some don’t tile great, but they are very clean 8k scans of large panels.

the designcraft leathers might be worth looking at too - they’re incredibly good.
