Reusable Teaching Guides aka RTG

These are sold where you find other One Stroke paint supplies.  Use these unique laminated worksheets to practice your strokes.  To learn and practice, paint right on top of the illustrations and follow the strokes, then clean and paint again until you have perfectly mastered the technique.  The blank RTG are a way to practice once you've mastered the strokes with the illustrated guides.
You can also lay plastic sheets over the worksheets in the One Stroke books (there are hundreds of them!) so that you can practice the strokes on the sheets.
Buy yourself an artists pad which is suitable for acrylic paints.  Use your book to practice in (don't cheat and tear out any pages) you can track your progress as you practice.
