Lace Curtains

Anyone ever made lace curtains? I am thinking about attempting those for my next project, but wanna know if I am crazy for thinking so lol Anyone ever made curtains out of anything? I know my husband made window accent....err.... thingie .....for one of our rooms and it turned out fairly well. We basically got cardboard, foam and the material and poof! a window accent thingie was born lol Altho, we may be redoing it - seems to not be holding its shape well, so may be looking into somethign a bit more sturdy. But not *too* heavy - as we dont wanna tear holes in our wall =)

Suggestions? Comments? =)
