I buy and try all the new marking pencils. They all seem to do the job. I like the ones that are easy to remove with no time involved. For light fabrics I use Frixion pens and for dark fabrics I use regular chalk. I sharpen the end to a fine point using a pencil sharpener. I have gone back to the water soluble blue pen for large area markings on light fabric now that I can buy the Blue Line Eraser product.
