About 15 years ago, I was invited to join a knitting group. I agreed to give it a try.

My mother had taught me to knit at 15, and I knitted in class throughout college and for a few years thereafter. Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also on crocheting, and I was on my way to becoming a highly productive crafter.

I've made countless baby blankets, sweaters, scarves, hats, caps for newborns. I take a knitting project with me everywhere, especially when I have to sit still and listen. As I discovered in college, when my hands are busy, my mind stays focused on the here and now.

It seems, too, that I'm part of a national renewal of interest in needle and other handicrafts. The Craft Yarn Council reports that a third of women ages 25 - 35 now knit or crochet. Even men and schoolchildren are swelling the ranks, among them my friend's three small grandsons. Last April, the council created a "Stitch Away Stress" campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneer in mind/body medicine and author of The Relaxation Response, says that the repetitive action of needlework can induce a relaxed state like that associated with meditation and yoga. Once you get beyond the initial learning curve, knitting and crocheting can lower heart rate and blood pressure.

But unlike meditation, craft activities result in tangible and often useful products that can enhance self-esteem. I keep photos of my singular accomplishments on my cellphone to boost my spirits when needed.

Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters, who 'routinely list stress relief and creative fulfillment as the activities' main benefits. Among them is the father of a prematurely born daughter who reported that during the baby's five weeks in the intensive care unit, "learning how to knit infant hats gave me a sense of purpose during a time that I felt very helpless. It's a hobby that I've stuck with, and it continues to help me cope with stress at work,provide a sense of order in hectic days, and allow my brain time to solve problems."

A recent email from the yarn company Red Heart titled "Health Benefits of Crocheting and Knitting" prompted me to explore what else might be known about the health value of activities like knitting. My research revealed that the rewards go well beyond replacing stress and anxiety with the satisfaction of creation.
