I love Frixion pens. Staples were giving them out as free samples last year at a business expo. The nice guy gave me a case of 48 of different colors when I told him that I use them for quilting. I was going to share with my quilt buddies but they had the free samples too. We swapped colors we liked the best. Come to find out the guy told one of the quilters as soon as he got rid of the samples he could go home and he had dozens of boxes to give out. LOL
