"If it is an unpainted canvas, sometimes it is helpful to dampen the fabric before you stretch it and let it dry on the stretcher bars. It is usually less likely to loosen up when the moisture from the gesso hits it."
Yep, vector art, and lots of layers! Working on some poster art in a style from the early twenties. All illustrator.
These first illustrations i posted are sooo tight, I'm trying to loosen up a bit.
I like your work as well.
