To me pillows are like blank canvases waiting to be decorated. In this case, I decorated with paint. This was a spontaneous project, so I didn't do much research into the proper way to paint fabric. I just dove in. It will be interesting to see how this pillow holds up over time, especially how it holds up to washing if that should become neccessary.
To achive painted stripes I started by applying masking tape stripes to my fabric. Then I painted.
Allow the paint to dry and remove the masking tape.
Sew into a pillow. I sewed my pillow into a sixteen inch square with an envelope closure on the back.
I like the results so much that I've already come up with other painted pillow ideas. Happy painting!
