This book does not give any directions on how to make window treatments at all. This book has "tips on the best use of particular designs, the desirable proportions in any room setting, and the quantity of material needed." It is difficult to imagine your own material in the different styles of window treatments because there are only line drawings. Overall, I thought it was a pretty useless book and I feel I wasted my money because I was looking for a book to give directions for making window treatments.
