Celebrate Penobscot Marine Museum's winter exhibit "Keeping Warm" at an opening with authors Sandy Oliver and Robin Hansen, and the Friendship Sampler Quilters.

11 a.m. to 4 p.m. — Meet author Robin Hansen, who will read her children's book "Ice Harbor Mittens," while showing slides of the illustrations. Robin will be at the museum throughout the day, signing copies of "Ice Harbor Mittens," her new knitting book "Ultimate Mittens," and her book of Maine mittens, "Favorite Mittens."

11 a.m. to 1 p.m. — Make a felted mitten ornament with education director Betty Schopmeyer.

1:30 to 2 p.m. — Cooking expert Sandy Oliver will talk about "Keeping Warm with Maine Cooking." Hear how Mainers have kept body and soul together with food from the 1800s to today. After her talk, Sandy will be on hand to sign her new book, "Maine Home Cooking: 175 Recipes From Down East Kitchens" and her classic book of heritage cooking, "Saltwater Foodways Companion Cookbook."

11 am to 4 pm — A resident quilter from Friendship Sampler Quilters will be working on her own quilt in the Museum Gallery, and there will be an opportunity for adults and children to learn a bit of quilting and work on a quilt "in progress." Those who work on the quilt may put their names into a raffle for the finished quilt.

The exhibit will be open through Feb. 24, Thursdays-Sundays from 11 a.m. to 4 p.m.
