Sisters Shirley Sessions and Sandy McCloud like to have fun. They also share a passion for animals.

The sisters combined their love of fun and animals to raise much-needed funds for the Humane Society for Greater Savannah with two popular Tybee events: Tybee Prom and the upcoming Jane Coslick's Holiday Cottage Tour.

The cottage tour takes place from 10 a.m. to 3 p.m. Dec. 6 and features a self-guided tour of some of Tybee Island's historic cottages with renowned interior designer Jane Coslick.

Sessions, a Humane Society board member and former president, says the funds raised from the tour will go to help the Humane Society fulfill its long-awaited goal to open a community low-cost spay/neuter clinic next year.

"Our first goal is to advocate for animals," she says. "We hope the clinic will make a difference in wiping out the number of homeless pets we have in our area.

"Our other goal is to have people see what you can do with an old cottage. Rather than destroy it, bring it back to life and make it a happy and fabulous place."

Sessions adds that Coslick is all about "happy colors."

"All of her homes she has preserved or decorated are always very happy colors," she says.

Coslick's first cottage, "99 Steps," will be on the tour, as well as the popular "Cottage on the Green" which was featured in the November edition of Coastal Living magazine.

"Jane is kind of shy, but she is all about the animals ... so she will be on hand throughout the day," Sessions says.

Tour goers can meet with Coslick from 10-11 a.m. at Chu's Department Store on Tybrisa Street for coffee and pastries while viewing unique bits of history and chatting about design and preservation.

Holiday treats will be provided at North Beach Bar & Grill from 11:30 a.m. to 3 p.m.

Tickets are $30 and can be purchased online or in person at Seaside Sisters, 1207 U.S. 80, Tybee Island.

Tour maps are posted at www.tybeefun.com.

After the tour, Coslick will be available for questions and to sign her book, "Cottages," at Seaside Sisters.

"A lot of locals like to ride their bikes or ride golf carts and just mill around and make a day of it," Sessions says. "If you choose to drive, the city of Tybee is not giving tickets for people on the tour. It's always nice to have their support.

"And all the cottages are decorated for Christmas. It puts people in the Christmas spirit.

"It's just a good thing. At the end of the day, I'm always glad that my sister made me do it," she says with a laugh.
