I have enjoyed the sharing of stories of customers and their demands. It reaffirms that one should know what jobs/clients they want to take on and what jobs they should refer to others. I have sold a few items at farmers markets and have been asked if I could do this or that project. Over time, I learned to say no and refer them on to others. It does come down to an education of the customer, that they understand the work involved, the time spent learning, etc. Even if you put a video up at a sales table, customers can sometimes feel that the speed and apparent ease that you work, the price should be lower. I tell friends that there is a recovery time for certain hammering operations (at least for me, a weekend/occasional hot metal pounder) and the cost of Ibuprofen to be added in!;)
My wife sews, but focuses and enjoys quilting, not making drapes or clothes, or even mending some item I ripped. Sometimes, customers feel since you know how to do one general skill, you can and will do all items involving that skill.
Thanks, everyone for your input and making this a great learning site!
