    Conceal Pop Up Orihon

    This year’s #LightUpPopUptober project was an adventure! The prompt for my day, the 17th, was “conceal.”

    I generally don’t cut things as close to deadlines as I did on this one. This has probably been the most #OverwhelmedOctober to date. I got everything worked out in time, and while I can see places that could use a little more polish, I think this is solid.

    This got a little hectic building the final piece. I think I have everything for a making-of video, though. That will likely be forthcoming after I recover a little.

    While there are some photos here, you really have to see it in operation to understand how it works. There is a short one-minute video showing me operating the orihon and cards.

    A pop up card of four hexagonal panels leaning together. The faces have spirals cut out and backed with translucent vellum. A white LED lights the pop up from the inside. The places where the panels were cut plus an extra spiral on each side are visible in the base of the card. The card sits on the panels of an all-black orihon (accordion book). Angled view from above.

    PinkEraserArtober x Witch Hat Atelier Crossover Stamp

    I needed a break from another project I have been working on last night. I keep noticing some of my previous eraser stamps fitting the daily prompts for #PinkEraserArtober2026. Yesterday’s prompt, “spell,” matched one on my to-do list. So, I thought it would be fun to give it a go.

    The ink jar is a variant of the ink jar I did styled after the Witch Hat Atelier anime recently. The circle in the upper left is for the “forbidden glow” spell Coco tries when she is first discovering magic.

    I did most of the carving with a narrow v gouge, with a little bit of craft knife work around the star shape in the glyph.

    Before printing, I painted the paper with UV-reactive ink. So, it glows under UV light.

    A lino-cut-style stamp carved from a pink eraser depicts a pot of ink, a pen or brush, and a circular spell glyph sits face-up on a print made from the stamp. The print is signed with an A and is sitting on a background of dark green crepe paper (chirimen).

    Griffin Passant Hand-Carved Eraser Stamp

    Recently, my mom has been enjoying a detailed history of her family since arrival on the American continent (prior to the American Revolution) researched in great depth by a scholar at West Point. Prominently featured in the book (and not at all the first time I have seen it) is the family coat of arms. One of the most prominent elements, apart from the vertically split blue and red field, is a griffin passant in argent (silver).

    The griffin is a mythical chimera with the head, wings, and front claws of an eagle, and the body of a lion. Griffins are associated with a range of positive traits, including vigilance, strength, and courage. There is also some associated Christian symbolism.

    I thought it would be fun to do my own heraldic-style griffin as a carved eraser stamp for my mom’s birthday. I did some with the silver ink and some with black. I also experimented with using watercolor pencils to create a parti-colored background similar to the coat of arms.

    The left half of a landscape-format piece of paper has been colored blue with watercolor paint, and the right half red. Stamped in metallic silver is a left-facing griffin (a beast with the head, wings, and front claws of an eagle, and the body of a lion) passant (standing flat with one claw raised) surrounded by a rectangular border. The carved pink eraser stamp that made the impression , stained with black ink, is standing on one long edge in front of the lower left corner of the print. The background is handmade black crepe paper (chirimen).

    There is a short video with commentary and some of the process of making the griffin prints.
