Made my own Seat cover today... Check it

just take your time. The hardest parts are the curved areas towards the front of the seat.

Make sure when you cut out your pattern, you are very precise. trace around your old cover very carefully, and then add 1/8th inch more material when you cut it out.

Also, i found that using pins to hold the curved parts the way they need to go helps a lot. use lots of pins, lots and lots of them, lol.

Let me know if you need any help, you can always PM me or yahoo/aim me.
