Dr. Teofilo Garcia (born 27 March 1941) is recognized for her important a Gawad sa Manlilikha ng Bayan Awardee for Hat Weaving from San Quintin, Abra. He is known for making the all-weather headgear, a well-made tabungaw, which can last up to three to four generations if taken care of properly. A tabungaw is a unique and functional headpiece which shields a user from the rain and the sun. It is made of the native gourd. It is hollowed out, polished, and varnished to a bright orange sheen to improve its weather resistance. Its inside is lined with finely woven rattan matting and the brim has a subtle bamboo weave for accent. Although Garcia has been a master artisan since he learned how to make gourd casques and weave baskets from his grandfather at the age of 15, he is principally a farmer. He spends most of his time tending the farm to send his five children to school. During the months that his land is not planted to rice and tobacco, or caring for his herd of cows, he devotes his land to planting upo (Lagenaria siceraria (Mol.) Standley) which he uses in making the tabungaw. Crafting the tabungaw, using simple hand tools, takes up at least seven days, assuming that all the materials are available. The following are the steps followed in making one: Plant and harvest the upo Refine the uway (rattan) which would be the lining of the tabungaw Weave the puser (bamboo) which would serve as the accent for the work His craft demands a lot of personal input. There is hardly any way for Garcia to source the materials he needs for his work unless he makes them himself. He has had to turn down large orders because he has no one to help him. There are times that he wants to give up but he fears that the art will end with him. His output is limited by his harvest of gourds. He can make up to 100 pieces in a good year blessed with good weather. Inspired by increasing orders, he plans on increasing the area of his farm dedicated to gourd planting. Garcia has not stopped innovating his craft. Each tabungaw is a product of years of study and careful attention to elements that make up the entire piece. Previously, he used nito, vine trimmings which he sourced from Cagayan, to decorate the outside of the head gear. He also expiremented with more locally accessible materials like bamboo. He believes that the tabungaw has potential as an export product. Now that his children are grown up, he has time to teach others the craft and is looking forward to the possibility. On 8 November 2012, President Benigno Simeon Aquino III confered the Gawad sa Manlilikha ng Bayan Award to Garcia during the awarding ceremonies at the Heroes Hall of MalacaƱang Palace. Garcia was cited for his efforts in keeping the traditional tabungaw-making alive and vibrant.
