Abstract: The objective of this study was to investigate the feasibility of turning cattle stomach into novelty leather and then leather product which would add value to end of cattle. Four pieces of green buffalo stomachs were taken through soaking, liming, deliming, pickling, tanning, neutralization, retanning, dyeing and fat liquoring operation. Then mechanical operations like drying and staking operations were also done. Some physical (tensile strength, stitch tear strength and colour rub fastness) and chemical (chromic oxide content, fat content and pH) tests were accomplished .The results of physical tests were poor compared to the grain leather as the composition of raw outer coverings of animals and their stomachs are different. The stomach leathers could be used for making coin purse, key case, bracelet, wrist watch belt, ear-ring, necklace, hair band, iPod case etc. as novelty leather product item.
