My latest hat - a cotton crusher. Even though the brim LOOKS firm, it's only the edge being held firm by nylon trimmer line (like in your lawn edge trimmer) It's VERY comfortable - yes, I'm working on the pattern - which will be a very easy project.
The repetitive actions needed for knitting and crochet can bring the mind and body to a state called a "relaxation response" that is quite similar to what people experience with techniques such as repetitive prayer, yoga, meditation, Tai Chi, and other relaxation disciplines. Research at the Harvard Medical School Mind/Body Institute has found that when an individual is crocheting (or knitting) his/her heart rate can drop 11 beats a minute and his/her blood pressure drops as well. These results can have significant health benefits for people who knit and crochet. Therefore, I am a man who crochets. I design my own crochet and sell patterns and finished projects.
