I am looking to buy curtains for my front door window. I need them to
be about 30" wide by at least 22" high. I don't see them in the
stores, so about how much fabric should I buy to make one? Seems to me
that most curtains don't go straight across, so I'd need more then the
30" plus whatever I would use to make a seam. But I don't know how
much more. Any ideas?
