If you have a window that could use a shade but you don't want to put up hardware for it, or you don't want to obscure the window, this DIY window shade is easy to make, takes a few minutes and looks pretty good, especially in a spare room, bathroom or laundry room. Image from Sherry Petersik.
You'll need some fabric (the amount depends on the size of your window), iron on hem tape and a way to hang the shade. If you want, you can also use a wooden dowel or rod to weigh down the bottom of the curtain so it hangs a little more nicely.
Make a template by taping paper against the window so you see how far down the shade will go and how wide it needs to be. You can also just use a measuring tape. Cut your fabric to the right measurements, adding 5cm at the top for mounting. Hem all the edges with the iron on tape, leaving a loop of fabric at the top and bottom for rods to hang the shade and weigh the bottom down. For a full visual step-by-step hit the link below.
