I caved and got some of those cosmic sharpies. I feel weird buting art supplies, but my last ones were 4 years ago(some colored pencils) so I guess its really okay. Still need a lightbox, but don’t know how much they cost or if I can buy one now. The one I have now is in storage in GA, is clunky, and older than I am.(It’s from when my mom was in fashion design school in the 80’s.)
