What are "ink designs"?
Ink designs are a single color line design that once stitched out onto fabric is then colored in with fabric ink pens. Think of it as making a "coloring book page on fabric". When you fill in the areas with permanent ink markers designed for fabric, the colors you apply and be soft or vivid; can be filled lightly or tightly, and each design is uniquely you!
Haven't tried this technique yet? Here are the pens at Amazon (shortcut ---> https://goo.gl/15rz7b) or you can find them at your local craft and sewing
stores like Hobby Lobby or JoAnn's. Finished project can be machine washed in cold water.
