I love my Practice Boards.! Whenever I get an idea for a design or just need to improve on one..I use my practice boards to help me achieve what I had in mind. Sometimes it's just nice to Doodle and see where it leads, whatever the mood or purpose I can paint what inspires me and when I make a mistake or want to move on to a different Idea, all I need to do is wipe them down with wipe or damp cloth and then I have a new canvas to start again..! These are definitely a great way to learn and grow in your skill level.
It was even larger than I thought, wonderful teaching tool.
