Vinyl top options

They wanted 45.00 per yard just for material. I imagine it would take 5 yards. Hell I have an industrial machine and a mini walker but keeping those seams straight and even would be more than I want to tackle. I've done car seats, bike seats and snowmobile seats but I think this would be best left to the pros. The price is kinda why I was leaning towards the SEM dye. The vinyl grain will be correct also that way. Heck I'd only be out 160.00 and my labor if I didn't like it. I found this post about dye and I might try the dupont dye.http://www.forabodiesonly.com/mopar/showthread.php?t=31412&highlight=vinyl+top+dye
