First, the fail message was that I couldn't understand how to do it (usually a skill fail, or at least it is in tailoring.)
Second, on Xhelp, I was told that it isn't possible to put stickers on the items I tried.
I don't know if there was a reason against this or it just was never considered. But I'm requesting the ability to apply stickers (and remove them) on e-notes, quick and lite terms, progias, printers, maybe even wallets and briefcases - or whatever else is currently not an option, yet used by many players.
I also request the option to not have custom designs for stickers available to the public, if that can be changed later, with not too much coding mess.
Is engraving an option? That may be too expensive for certain items.
