Make Your Own Curtains
My son wanted horse curtains and they are expensive to buy. Instead I used a 50% off curtain at the fabric store and made them myself.
FYI: This post has 18 pictures and a lot of words.
First measure your window vertically and horizontally. The general rule to determine how much material you need is to take the width of your window times 2 or 2.5. That will give your curtain the extra drape it need to look nice. So I needed 2 panels 45 inches wide. Since material comes in 44 inches I just needed to figure the length I need.
To determine the length needed: Subtract the length of the tab from the length of the window. Add inches for the hem at top and bottom. Take that amount times 2 and that is the length of the yardage you need.
