Maxine James, a 79-year-old retiree, will make her arts-and-crafts fair debut at Saturday's Spring Arts and Crafts Fair. James, seen here in her Lawrence home, creates decorated vases and bowls with jute rope and fabric which she fills with cacti and succulents. She calls her business Cactus in a Jar.

Celebrate Pi Day early this year with a day at the races. Also on the docket: arts and crafts, movie magic and a sampling of classical Indian music at the Lawrence Arts Center.

Spring Arts and Crafts Festival

9 a.m. to 4 p.m. Saturday, Douglas County Fairgrounds, 2110 Harper St., Building 21

The Lawrence Parks and Recreation Department’s 15th annual springtime crafts show returns this weekend, bringing with it 80 exhibitors from across the Midwest to the Douglas County Fairgrounds.

Among the varied items for sale this year: stained-glass jewelry, dog collars, homemade honey, ceramics, hair accessories, home furniture, baked goods and goats’ milk soap, just to name a few.

Pi Day River Rotation Half Marathon and Pi Miler

9 a.m. and 8 a.m. Saturday, respectively, Lawrence River Trails near Eighth and Oak streets

This year’s Pi Day races, sadly, fall a few days short of the actual Pi Day, but race organizers promise to make up for it with plenty of pi references and, of course, pie.

Participants in the Pi Miler (the punny course totals 3.14 miles, natch) or River Rotation Half Marathon will end their treks on the Lawrence River Trails with homemade pie at the finish line.

Online registration has already closed, but participants can still register at packet pickup Friday from 2 to 6 p.m. at Ad Astra Running, 16 E. Eighth St., or the day of the races at the trails. For more information, visit www.trailhawks.com.

“Some Like it Hot” screening

2 to 4 p.m. Saturday, Lawrence Public Library, 707 Vermont St.

As part of Healthy Relationships Month, the library, in this weekend’s free Health Spot movie, is screening the 1959 classic “Some Like it Hot” and talking about relationships, “romantic and ribald.”

The Billy Wilder flick, hailed by the American Film Institute as Hollywood’s greatest comedy, has a bit of both. Marilyn Monroe, Tony Curtis and Jack Lemmon star in the wacky, cross-dressing satire that at the time of its release earned a “Condemned” rating from National Legion of Decency.

Classical Indian Music Benefit Concert

5 to 7 p.m. Sunday, Lawrence Arts Center, 940 New Hampshire St.

This afternoon of classical Indian music — which also includes some “East-meets-West” fusion — benefits the young monks at the Chhairo Tibetan Buddhist Monastery in Nepal.

Classical Indian violinist Purnaprajna Bangere, bassist Jeff Harshbarger and tabla player Amit Kavthekar are all slated to perform.

Tickets cost $10, or $8 for students. Buy yours at Zen Zero (811 Massachusetts St.), La Parrilla (724 Massachusetts St.) or Genovese (941 Massachusetts St.) restaurants.
