Shaw-based illustrator Lauren Friedman owns well over a hundred scarves, from patterned silk squares nabbed from her grandmother’s bureau to swoopy modern mufflers. “No matter how you feel about your body or what kind of a hair day you’re having, a scarf adds an exclamation point to what you’re wearing,” says Friedman, who also blogs at Inspired by her collection, Friedman wrote and illustrated “50 Ways to Wear a Scarf” ($15, Chronicle Books), a whimsical new TIY (tie-it-yourself) book full of drawings and directions showing how to create head wraps, neck knots and more. We followed her around on a recent Friday, photographing her as she tied one on at local boutiques. She’ll be signing books and doing demos May 8, 4-7 p.m. at Proper Topper.

“It’s about telling a story when you get dressed — who am I today?” Friedman says, as she ties a simple, drapey bow in a Sayami wool scarf ($60, Proper Topper). This style will work on almost any long, rectangular piece, and looks good prettying up a boyish look, say a blazer and jeans.

1. Drape a long rectangular scarf around the back of your neck so the ends are even in front.

2. Tie the ends together once, leaving the knot at the level where you’d like the bow to hang.

3. As if you were tying your shoelace, create a “bunny ear” with each side of the scarf and knot together in a bow.

4. Finish by adjusting the ends as you see fit.

Two simple knots can turn a large, oblong scarf into an elegant jacket-y thing. “It conveys drama, the way the scarf flows and billows behind you as you walk,” Freidman says. “It can be casual, dressy or sexy,  but most importantly, it’s such a gorgeous way to show off a really beautiful scarf with nice drape.” Use a recycled sari silk scarf ($42, GoodWood).

1. Fold the large scarf in half lengthwise.

2. On the opposite side of the fold, knot the matching loose corners together, creating two knots.

3. Insert one arm through the long open end of the scarf and out through one of the short open ends. Bring the scarf behind you and repeat with the other arm, so that one knot comes over your right shoulder and one knot comes over your left.

4. Finally, adjust the scarf so that the knots fall below your arms, allowing the scarf to fall over your shoulders.

“I like vintage scarves in bold, bright patterns,” Freidman says. Here, she tied a 1960s Norell silk one ($24, Treasury) into a retro head wrap. It’s paired with a 1950s shirtdress ($75, Treasury).

1. Place a long scarf at the back of your head at your hairline.

2. Bring the ends forward, tying once above your forehead.

3. Tie the ends into a bow. Finish by adjusting the bow as you see fit.
