start with a toner (not inkjet) backwards-printed image on regular paper and a wood block prepped with a clear wood varnish (to prevent ink bleeding). sounds complicated. okay, maybe getting the materials is a little work, but it only gets easier.
tape image onto wood, image face down. you got this.
using your handy dandy Toner Cloner Marker that you just purchased, press and ink over the printed image once. careful not to over ink or the image will bleeeeed. careful not to underink or the image won’t transfer over. lol.
after inking, using a sharp flat object (like the side of a ruler), press and slide to flatten image to ensure transfer. sorry i forgot to take a photo for that part.
