Random hitomezashi patch.
It has two mistakes, at least.
But it’s doing its job as a patch perfectly. #mathart #embroidery #sashiko

Take a grid, for each line add 1 to all points on a randomly picked side of that line, paint points black if the result equals 0 to 1 mod 4, and you get a hitomezashi pattern.
But what if we do this for an arbitrary pattern of curves instead of a grid?

Here’s the last thing I made for #ArtAdventCalendar that I didn’t get time to post. It’s a small cross-body bag, fully lined. All hand stitched including the pomegranate hitomezashi pattern & silk trim. Internal patterned fabric is from Japan, gifted by the friend who the bag was gifted back to! 😁

I thought I'd try posting a #pico8 cartridge to the official site.
I'm starting with one I haven't shown off yet: a hitomezashi embroidery pattern editor! See the link below for a live version and more background info!

Done!! My little #hitomezashi #Heatmap experiment is complete. While not a particularly interesting composition, it definitely proves that you can move through bands of colour within a hitomezashi pattern... Neat! 📊 #dataviz #dataart #crossstitch #embroidery

speaking of web generators,
I got the Hitomezashi Pattern Generator
(companion to @hitomezashibot.bsky.social ) up now too!

The second afternoon session at the Bridges #MathArt conference is "Hitomizashi Galore": The first talk is by Katherine Seaton on "Interleaved Friezes: Celtic Knotwork and Hitomezashi." (archive.bridgesmathart.org/2026/bridges...) She talks us through which Friezes can be done via Hitomezashi. (1/2)

Goals ( or are they targets?) achieved:
1) Successfully modified Hitomezashi design on @turtlestitch.bsky.social so it embroidered on my machine
2) Used it to mend two garments #visiblemending
Small steps, but making progress! What next?

Such an amazing “workflow” in which hitomezashi, heat sources and complex mapping gives beautiful patterns.

#MathArtMarch Day 22 prompt is hexagons. So I've skipped ahead in my plan to methodically investigate colour exchanging symmetries in hitomezashi, straight to some hexagons! Reflection leaves one colour fixed and exchanges the other two, while rotation through 120 degrees causes "all change".
