I buy the plastic cutting mats from the dollar store $1.00 for a pack of 2-3. They are easily cut with scissors (not fabric scissors please). You can easily see through them or use a light box to draw your designs with fine point magic marker. Cut the pieces(s) out, trace around them onto your fabric with the fabric marking system of your choice. Then, when you cut them, they will be consistent. Cheap & effective! I do it all the time!
