Are there any CHEAP sources for the American/Bicentennial tartan material in a thick enough fabric for a kilt.

I like it, great for July 4th, Memorial day, flag day, etc, BUT I would rather not spend over $120 for the fabric to make a kilt out of it. There's not enough time for this year, but it has me "in the spirit."

Do I have to get a Sport Kilt in it and convert it into a better looking model?

Thanks,
