What kind of seat are you making? Saddle/solo, or traditional? If its a saddle solo making a leather seat cover isn't to hard if you get yourself a few basic leather working tools. I've made few in the past, I've made loads of holsters, I learned more out of necessity than anything. I'm left handed and left handed holsters cost WAY more than right handed holsters, so I bought a side of leather and made my own. Haven't noticed anyone hear on the forum doing much leather/seat work though. But I cant really speak for the group.
