A smooth work surface is helpful when working with paintstiks. Any texture placed under your fabric will show through as you apply paint to your fabric. You may wish to cover your work area with plastic to keep your work surface free from stray paint.
Paintstik colors are permanent once they are dry. Wear old clothes or use an apron to prevent accidental “enhancements” to your wardrobe.
Fabric tends to move as you apply color. You may find it helpful to tape your fabric to your work surface to prevent shifting while you are working.
