Blue Zen started out as a drawn zentangle that I enlarged and transferred to a hand painted cotton. When I enlarge something, I transfer it to fabric by hand stitching with a contrasting thread through the tissue copy. It is more labor intensive, but you don't have to worry about a pencil or pen not coming out of the fabric. Do watch out for the color of thread you use. Once I used a dark green on a light fabric and when pulling out the basting after the stitching was done, it left dye behind. That's the time you get creative to cover the mistake/design challenge up.
