I designed these cozies to add a little class to my occasional coffee-to-go instead of the paper sleeves they give you at the coffee shop. I had previously made some cozies using worsted weight yarn, but the result was too bulky-feeling for my taste.
The cozies use either #10 or #3 Crochet Thread. The multi-colored one uses #3 size thread. When my wife saw it, she asked if I could make one in Red and White to match Starbucks new "Holiday" cup. I didn't have #3 thread in those colors, so I made her one using #10 thread from my stash.
I've added the pattern, which contains versions for both thread sizes, to my Ravelry and Etsy Stores.
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.
