I'm think I'm with Glitter Gypsy: I don't mind light tinting, but heavy staining does bother me.
With one exception, where I've discovered it is actually desirable - Last night I was setting up some new clear sets in CD cases, and there were lots of small sentiment phrases and words among them (one set had many), and I was struggling to figure out which was which so I could place them against the index sheet properly. So I purposely took all the sentiments and stuck them on a storage panel and stained them with my Charcoal chalk ink. Now I can see which are which! I will probably do that with all my clear sentiments in all my sets.
I know what you are saying about not being about to see through your clear stamps, Sue, but with a clean rubber stamp you can see the ink on the stamp unless it is a light shade, which is when you just have to make sure the whole thing is wet looking. With a darkly stained clear, you can't see any ink, ever. You always have to do the "wet" check.
I don't know. Maybe my lighter chalks won't stain so badly. Maybe I'll just start to not mind it.
