Each strip gets pinned onto cardboard so it does't move around for when I paint the front edges. When dry, I remove the pins, and paint the fabric edges themselves with matching paint, one colour on one side of the strip at a time, allowing the paint to dry in between. Then the back edges get painted, and glitter paint lines get applied on the back over the stitches from the beading.
Top strip is just beaded. Middle strip has front paint. Bottom strip has back paint and glitter.
