Hello from central Texas. How do you get chalk lines off muslin fabric?? I've never quilted, but when I saw my first Crayola quilt I decided to start small with a wall hanging. After completing the top, I chose to quilt using straight,cross-hatch stitching since I don't know how to do free-motion yet. I used a chalk marker to draw the stitching lines on the muslin panels that contain the crayoned designs; messed up some of them & have a few double lines, and can't get the mistakes to come out of the fabric. Tried a dry toothbrush, which only faded it a little. Then tried a soft wet cloth & no luck. On advice from a quilter friend, I washed it on gentle cycle with a bit of detergent, which faded but did not remove the chalk lines. Since it's muslin surrounding the design, it's still pretty noticeable. Is there any hope?? Thanks!
