New Interior

well the interior of my 88' 2001 is pretty beat up, the vinyl is cracking, ripping, tearing and the seat bases are all pretty much rotten. i asked my dad if it would be possible to do the interior ourselves and he thinks we could do a pretty good job because my mom is pretty good on the sewing machine. (im only 15 thats why my parents are involved in my boat projects still ahah) i was also thinking about a new design for the back seat that incorporates a ballast tank or storage or a sundeck or something. also a design for the bow because i have a 12" up there right now but im wondering if anybody has done anything cool to make it look stock? so if you have any ideas throw them this way. also if you have any advice on how to make a good job on the interior it would be greatly appreciated. thanks alot
