Here are some thoughts for those who are hesitant to learn a new craft skill.
If I was going to write a book, I'd call it...
LISTENER'S GUIDE TO THE COLORFUL WORLD OF MISTAKES.
I have unpicked hundreds of rows of knitting in every possible sort of yarn...wool, cotton, acrylic, bamboo.
I have unpicked thousands of machine stitches...after sewing fabric back-to-front, upside down, and wrong side out.
I have never done a single cross-stitch that did not require several hours of undoing and redoing.
But best of all is my very first attempt at knitting. I did a basketweave sweater for myself. It was beautiful. It took forever. Did I mention that I learned to knit from a book? The book failed to mention that when joining yarn at the end of the ball, it is best done at the beginning of the row. I joined it wherever it ended. Twelve months later it started to unravel at 10 different spots. Moths would have been a more merciful end.
This thought: mistakes happen...rather than fear them, I've learned to stay awake, and learn from them, and laugh (later) that some lessons are best learned only once.
