Most of my creating is done alone. It works best when I can somehow control inbound and outbound telephones calls, emails, texts, facebooking, etc. I know artists that work collaboratively with other artists and sometimes I am lucky enough to do that, but for the most part creativity comes when it can.
Other things can get in the way, the need to go to the grocery store, clean the house, do laundry, work in the yard, and participate with family and friends. It is amazing with all we do that any of us have the time to create.
I have found some of my best ideas in driving school (they thought I was taking notes), in a bar on a napkin and in a conversation with a customer. It comes when it does and when it doesn't it is best to walk away from what ever tools you use. When I haven't done that - some of the ugliest jewelry in the world has been made. Thank God for scissors!
I am blessed to have many artists as friends. We share the coming and going of the muse. Some have more challenges than others in finding the time, space, money and other resources to create their vision. The important thing is to find the way to do it. - then do it. It feeds the soul.
