** If you want your drapes to always puddle, then you can skip the measuring and jump right to hemming. If you want your drapes shorter, so they don't hit the floor, use this pin to measure up from for your desired length.
Textile Love: DIY Pinch Pleat Drapes - Pleating and Finishing
Great tip!!!! Buy tablecloths to use as draperies....much less expensive, already hemmed, meant to launder often, and many patterns and colors available! 60x84 or buy 60x104 so you can hem them AND still have matching fabric left over for pillows or other coordinating pieces!
