The Yellow tracing paper is the same consistency as the pattern's we find in all the pattern's we buy ( Mc all Simplicity, from the large drawers after finding number in catalog.) . Does not bleed ( can use marker) very thin and same color. This can be bought at office supply stores. I have sent this address only to show an example.
I love this.. Great on needles. I have used freezer paper, copy paper. anything I can get my hands on.
During college days we called this BUM.. Don't know why.. But it is great stuff !!
Good luck !
