I have had good and bad experiences with this type of client. What I do now is to hold their hand through the design process, provide pics, etc, then, once the design is complete, they sign an approval form and I make the item...no more changes. Since I have been doing that I haven't had any problems with clients not being happy with it,since they are somewhat invested in it and see just how much effort goes into creating a custom piece. but there are still times you just have to say no. I usually put it on me...I'm probably not the best person for this, but I will give them some names if they would like...that sort of thing. Doesn't cost me anything to do that and they don't feel like I've been rude. Good luck.Dave
