Odd... I know I saw something, but I did a search for 'dye' and came up empty. Oh, well...
So here's my question. I've never dyed wood before. This is part of the ongoing picture frame project. Doorlink's favorite color is purple... But I can't afford to make a dozen frames out of purpleheart, and anyway I don't want them all to look the same. I'd also like to do some in blue. Keep in mind that the frames will be routed, so sanding all those nooks and crannies evenly would be a big hassle. I'll likely be using sycamore, though pine would do for some of them. I've been finishing frames with poly so far, or thinned poly, or a poly/BLO/naptha mix, wiped on. I've never tried any other finish.
So, given all that, what dye would you use? It has to be so failsafe that even an idiot like me can't mess it up. It has to dry fairly quickly. And I really really don't want to be raising the grain on these things. They're frames for posters, so they need to look good over the next five to ten years... they ain't heirlooms, and I ain't framing an Ingres (well, at least not an original). Oh, and did I mention: the cheaper the better?
