- 21. Past , Present& Future Prospective of Pina Fiber…… During the 19th century , pina fabric was in demand worldwide. However , production ceased and all but disappeared when cheaper cotton fabrics took over .

- 22. Past,Present & FutureProspective of Pina Fiber…. It began with marketing the pina barong (embroidered traditional formal garment) locally which eventually influenced the elite.This campaign elevated pina fabric to become a symbol of status.
- 23. Past,Present & Future Prospectiveof Pina Fiber Domestic support also marked the beginning of a foundation dedicated to the revival of Philippine arts , crafts and culture. Fortunately , traditional pina weaving has survived being dangerously close to disappearing and production has since begun to flourish . Now , once again , pina fiber has great prospects for the future.
