Photo of a cross stitch bookmark with three hands on it: on the left, a skeletal hand holding a sewing needle; on the right, the same hand, but with muscles and tendons visible; and in the center, a full, skin-and-flesh hand holds a needle aloft. The bookmark is on navy fabric with a fringe on each end, and is photographed held by both a human hand and a skeletal one.

The pattern for the Pi Day Nonograms is up! It's the same design as the puzzles, but all together for ease of stitching. There's also a Pattern Keeper version, as well.

The different numeral systems are, from the top: Babylonian, Maya, Chinese, Arabic, Roman, and Burmese.

It's a quick game, and a fantastic one-- apparently the dev lead is a history prof, and consulted with other historians during the making of the game, and it shows.

Also it lets you live out the dream of going to a museum, touching all the objects, and then getting to poke into the back rooms.
Screenshot of walking through one of the Blackhaven museum exhibits titled "The War Comes to Blackhaven". Various Revolutionary war era objects and paintings are on display. Kendra is holding up a small tablet with trivia questions on the exhibit.

You play Kendra Turner, an intern at a historical site: "Blackhaven Hall", a plantation that burned down during the revolutionary war and has since been restored. Kendra's the newest hire, and-- notably-- the only black employee, but she needs the credit for school, so you do what you gotta do.
Screenshot of Blackhaven hall at night: a large colonial-era red brick plantation. A solid half of the original construction is missing, and has been replaced by a modern glass-and-steel reproduction.

found this post open in an old tab--- kerning for the second one is a little wack, but something like these? just as like a fun free gift kinda deal. :) I can tweak colors/spacing if you'd like, and pop either/both into a pattern maker and get a PDF or Pattern Keeper file.
A simple pixel art cross-stitch of the quote with a swirling border. Another pixel cross-stitch with a fancier border. The spacing for the quote is a little odd, though.

"NOT NOW--I'M WATCHING MY SOAPS", Martha Carter, 1981, in "Just Cross Stitch" Issue 1. A black-and-white pattern. Surrounding the main text is a border with the names of different soap operas: 'General Hospital', "Days of Our Lives', et cetera. "True Crime Cross Stitch", MollyPopCraftingCo, 2025. A digital cross stitch preview that says: "Leave me alone. I'm listening to true crime podcasts!". The text is surrounded by pixel-style skulls, knives, axes, guns, and various sparkles and flourishes.

tumblr crowd convinced me-- working on cleaning up my no-ai-in-cross-stitch extension now. it's not at all polished, but it does work!
Screenshot of an Etsy search page with several AI-generated patterns displaying at half opacity with red borders around them. In the corner of the window is a Firefox extension info popup with ASCII art reading "No AI in Cross Stitch". Below it are links to flag a shop for AI patterns, report an error, and submit an appeal.

Someday I'm gonna live in a marsh, you take my word for it; milkweed and crayfish and Canada geese-- and me in a tall pair of waders. 🌾

aaaaand a closeup:
A small and ornate mathematical cross stitch on blue fabric with white and gold thread and pearl beads. It shows how sine and cosine can be found in the position of a point as it travels around a circle. The circle is in the top left, with a point marked by a pearl bead. Sine (charting the point's vertical position) is drawn to the right of the circle, and cosine (charting its horizontal position) is drawn below it. In the lower right corner of the cross stitch is a white-and-gold stylized unit circle, with french knots representing the coordinates of the points on it.

It's a late night, and probably's already morning somewhere, so-- clue 6 is up! Have at it! #nonogram #crossstitch

A nonogram with the number six and a little coolguy face made in it. Neither the six nor the coolguy are actually a valid solution to the pictured clues.
