I was finishing up my SAQA auction quilt and needed a small amount of powder blue Pearle Cotton thread. I had a light gray and a dark blue, but no powder blue. I didn't want to drive to the fabric store that has Pearle Cotton (20 minutes each way). So I took the gray thread and Inktense Watercolor Pencils in blue and a green and white and colored the thread directly. Then I dipped the colored thread in water. It was a little too intense a color so I folded and twisted the thread to double it up with uncolored thread. Some of the ink transferred to the uncolored part of the thread and I got the color and intensity I needed. The Inktense is permanent when it dries.
