Orange club, and some fun stickers this time. (Am I allowed to claim 2/3 of a century yet, or is that next time?) #66 #GiveBlood #NHSBT

Mmm, chocolate style flavoured coating approximation (but hopefully my blood is actually real and can help someone!)🩸💉🅾️➖ #65 #GiveBlood #NHSBT

Wow, they really picked a bad place to store all these bicycles

#64 is a power of two, so I am fortifying myself with the power of two post-donation snacks (obviously, Orange Club and ready salted Seabrooks, the best snacks). #GiveBlood #NHSBT

Photo of my arm and lap, with a plaster on the inside of my elbow, holding a plastic cup of squash and on my lap is a packet of Ready Salted Seabrook's and an Orange Club chocolate biscuit

Today's #hackjam successes: no actual machine knitting, but made a new handle for the knitting machine case as the plastic one had snapped, and also did a bit of crosswords, a bit of hand knitting and changed the batteries in the doorbell.

Spent a deeply enjoyable morning yesterday hanging out with @studioknotunknot.bsky.social and knitting some cellular automata! If you want to get better at machine knitting, or hooking a knitting machine up to a computer, Madeleine does fab training in both! 🧶🤖🌈

Photo of a knitted item on a bench. It's knitted with bright blue and pink yarn, and the pattern is Wolfram's cellular automaton with rule 30, which gives a chaotic jumble of pattern with occasional isosceles triangles in it

Meanwhile on Facebook, that time we did a Star Trek event and we were in the green room sewing tribbles for stage decoration

Photo is of a pile of furry balls on a table in various shades of white, grey and brown, and in the background are a room of people sitting at tables and chatting
