Forget about french knots -you can just paint them on! A fun alternative to stitching -use fabric paint to embellish your felt! We loved the flow and precision of this narrow tip bottle.
This fabric paint is listed under the cactus project tools and it has a nice small tip that makes it easy to use. I recommend trying a few dots on a scrap piece of fabric or paper before applying it to your project. This will help to gauge the amount you want overall.
