I was taught to choose my finished art materials for the long-haul - lightfast pencils and a surface that will last decades, if not longer.
Finding acid-free, lightfast, durable paper & board is getting easier. I use Crescent or Strathmore Illustration Boards and Strathmore or Mi-Teints Paper (though lightfastness is an issue with certain dark Mi-Teints colours).
The pencil brands I choose are various, and all dependent upon lightfastness. I have Prismacolor, Derwent regular and Colorsoft, Lyra, Faber-Castell, and Caran d'Ache. I have some Rembrandt as a gift from a friend, which I use sparingly.
To pick the most lightfast colours,
All stock resources have a list of rules up front, so here's mine:
Only the "Stock" folder has stock.
Stocks that I pre-cut can't be used for commercial purposes. Use on DA is fine.
I don't require credit on the pre-cut stock. I personally find it helpful, though, when the origin of stock resources is shown - it helps to find nifty things and new ways to use nifty things.
These rules/guides will change as I begin uploading personal reference photos for stock use.
Hopefully, I add something of use to the DA community!
