How did you make that?

I posted some comments about my silverware jewelry the other day on Craigs List. So now someone has asked for details on how I made them. I'm curious about your thoughts on this? Some of those nasty people on CL attacked the poster. I admit sometimes at craft fairs someone will ask me how I make something and I think to myself "how rude". But online the question seemed different. I answered her questions without thought. There was so much work involved when I was learning to make those silverware pendants. Why not give someone else a little help. So what do you say when they ask you your secrets?
