Is it patriotic to make bed sheets out of your flag?:
No it is definately not. There are several rules governing what you can and cannot do to the flag (assuming you are talking about the greatest and prettiest flag in the world - Old Glory). Check the site below to see them.

FYI - Bushy Bush desecrated an American flag by signing his name to it for a "fan" (I call fans of Bush "traitors"). He is thereby a traitor to this country, and should be tried and condemned as such. Just my thoughts on the subject. Can you tell I didn't vote for him?
