I don't know of any patterns for drapes - since the tissue paper alone would be difficult to get into an envelope. However, there are probably directions on the Internet about how to measure for draperies, work with pleating (if that's the style you want) or casings, etc.

Way back yonder, I used a book published by Singer, I believe. They had one "How to Sew Draperies", and another one, "How to Sew Curtains". I've included a link to Abebooks.com's listing for the one on draperies. Bear in mind that it was published back in the 70s, and you may find free instructions on the Internet.

Here is a link that might be useful: Singer Book, How to Sew Draperies

Those books Donna mentioned are more than likely available at your local Library.

Sunset also has books out on the subject and many others.

The pattern books do sell what they call patterns,but all they are are usually cards or paper telling you how to measure for the kind you want,and i don't think you want to pay 15.00 and up for that when your library has the same info for FREE.
