Pat Kolesar, well-known doll and bear artist and a fixture at doll and bear conventions as well as on home shopping channels, died on Wednesday. Even if you didn't know Pat personally, chances are you knew who she was--her purple hair and her bright smile and personality added joy to many doll events. Her dolls and bears were sold by several companies, including Barton Creek. Funeral arrangements are being completed now. Her family has requested that in lieu of flowers, contributions can be made to the American Cancer Society or the Pulmonary Hypertension Association. Everyone in the doll world extends our deepest sympathies to her husband Don and their children and grandchildren.
