There is a You Tube channel with the moniker @CayDenise. It is not me.
I saw a zine post recently in which the artist shared how to create taller-than-wide zines on copy paper. It's actually simple and just a matter of folding the paper a bit differently than for mini-zines. In creating this kind of zine, the art (drawing, collage, or writing) will be constrained in ways that are unexpected -- as I learned in putting this one together. The materials used for the project were cut-up pieces of unused art and silhouettes from cut-outs. My approach was to simply play. I like how it turned out and its simplicity. The cover page is the one with the purple oval. To follow the pages, move right, then up, around, and then down to the purple and orange page (the back cover). The video below is a quick tour of how it looks folded with the pages being turned.
