|I have been trying to find a pencil, or marker or something that doean't bleed through when I trace my patterns. I love Nancy's Notions Pattern Tracing Material. Because it is very thin but very strong and the best as for seeing through. But everything I tried bleeds though and marks up my patterns. And pencils don't cut it. Can hardly see them. Well I have found the perfect thing, and it has been in my house for years. Crayons. The perfect marker doesn't bleed through and very visible, and any color you want. And inexpensive. I found Crayola Jels to work the best for me.
