I made a cuff bracelet - actually many cuff bracelets. It's artisan jewellery and that is what I do. I submitted a bracelet using beads on memory wire. I struggled with the memory wire and it cost me a flare up of arthritis. I threw it out - well figuratively speaking I threw it out. It landed in such a way that it looked pretty cool on the wrist. My sister was the inspiration and now she wears both bracelets.
Well the falling of the memory wire bracelet was serendipitous: it saved its life and sent my mind off in search of a new memory wire technique.
The next serendipitous happening occurred just about a week ago. My sister and I were watching TV and she suddenly noticed an incomplete cuff bracelet on the table. The only reason it was still in existence is that I hadn't cannibalized it (cut apart and beads and salvageable wire returned to my bead wall). She expressed her delight. Now I have to finish the piece.
Sometimes a failure in your eyes is a success in another's. When you are unhappy with your work and it is not technically flawed, put it down for a day or two. If your attitude doesn't change, stand it in front of a mirror and look at its reflection in the mirror. Pretty good, isn't it!? If your attitude still doesn't change, ask the opinion of somebody else.
Except when the work is technically flawed, don't automatically do the frog stitch (rippit, rippit) when you make a 'mistake.' Is there some way of salvaging what you have done? Maybe you didn't make a 'mistake' at all. Why are self-taught people inspired and inspiring? They had nobody telling them they did something the wrong way.
Take care of your ego, it gets you up in the morning, ready to face the world. Don't tell yourself you are a failure, or you can't do __X__. There are enough people out there who are happy to tear you down - don't you be one of them. Look for the serendipity angel - she exists.
