I started my project with a simple IKEA panel. Determine how many stripes you want as well as what size each stripe will be. Beginning at the top, start to measure down the curtain marking off the area for each stripe to be painted. My stripes are each 12".
Using your marks to keep your line straight simply lay your tape across the width of the curtain. I used my trusty Frog Tape for this project. Once you have the tape in place smooth it down to ensure that no paint can seep underneath it.
Apply a generous amount of paint to your roller and begin to paint the taped off area. If you are using a darker colour give the area a quick second coat just to be sure the area is evenly covered. Tip - Use a flat or eggshell finish. Just like with walls, glossy paint will highlight imperfections (not that you would have any imperfections).
Once the painting is complete remove the tape. Make sure the paint is completely dry before hanging the curtains. Hello easiest diy ever!
One more look. Now off you go and paint some curtains for yourself.
