I am fascinated by the concept of making mistakes. And to me, it really is just that- a concept. If we look at our creative process as a series of experiments, than each stage is necessary to reach the outcome that we're most satisfied with. What might be considered a mistake is actually a necessary step towards discovering something more effective or to learn a new skill.
Nothing can teach you this more clearly than writing a craft book. In writing 28 patterns, I learned a great deal about the necessity of prototypes. Whatever I envisioned in my mind usually took several attempts before it reached its final version... often different, but always better than what had been planned.
I've kept many of those
Here's what I learned about working with my leather from SCRAP:
-A universal needle works beautifully with thin supple leather
-Folding that same weight leather in half transforms it into something exceptionally strong and sturdy (great for a handles)
-Using contrasting thread is asking for trouble, but has potential to be striking.
Have you learned anything recently from something you considered a mistake? Perhaps it was just a step in the right direction. And hey, seam rippers are very effective! Wish I could use them in all areas of life!
