I think a chop is supposed to be square. I came up with one I like, but it isn't square. This bothers me.

If you rotate a 2d dungeon 45 degrees and scale y by 1/2, you get an isometric dungeon.

Another thing where I have room to improve! It's so freeing to be so imperfect. Zentangle®️inspired.

I'm trying Zentangles®️ except on iPad, so really Zentangle-inspired. So far I'm not at all good at it. Got a good chop though:

In Taror, a card is called "reversed" when it appears upside down during a reading. This is said to imply resistance, blockage, or even reversal of the card's usual meaning. However, a surprising second card has emerged from the San Marco discovery: a […] [Original post on mastodon.social]

A recent discovery on San Marco, near Venice, suggests that there may be as many as 30 "major arcana" in a Tarot deck, rather than the 22 known to date. The cards discovered are seriously water-damaged (Venice, y'know) and thus far only one card, number XXIX […] [Original post on mastodon.social]

What it is, Ice Cubes only lets me mute for a max of 7 days, and my feed is so full of horror that muting becomes most of my Mastodoning for two or three days. I need a break from the horror, if I am to persist at all. Maybe I need to create an account that just follows artists and cat photos.

Procreate dual color brush I created to draw vine-like things, dark outside, lighter inside. For some reason, it has a thin white border when crossing a prior colored area. No idea why.

RE: mastodon.art/@welshpixie/1157131164… This little zine got me started having fun drawing again. I'm not very good, but I'm better than I was, and way better than folx who don't draw at all.

I follow some fine artists and craftspeople. And still, I'm a bit proud of my progress, tho the artists and craftspeople have little to fear.

Oh my! procreate can have a dual line brush! This pleases me. Prospects are good!

Satisfactory, possibly finished inking. Still the flaw, might not fix.

Progress. Left side curves pretty good. iPad helped. Still major flaw, might let it be. Doing better than I was, the primary measure of comparison.
Complex Celtic knot, left loops connected, looks pretty good.

Again, not all cleaned up but kind of nice. Wish I had some use for these.

This one, unpolished, surprised me because the two top outside parts are the same, not symmetric. I've done it twice, and don't think I've made a mistake. If you see one, let me know.

Hahaha yesterday (Dec 26) was my birthday and none of you even knew it! In other news, I rather like the design below and wonder what to do with it, and things like it.

I read that there are 12 unique shapes in Celtic knots. I've found ten, counting reflections as two. Have I missed some?

Inspired by @welshpixie, I'm fiddling with Celtic knots. Wondering if there might be some coding fun here. But they're good practice for my fading drawing skills as well. Might bring me back to drawing. It could happen.

I will color a 3x5 card blue and pick up the postage to send it to you, not for 18 million dollars, but for a mere $180,000. Much better deal than the Yves Klein one. For a digital version, see the attached. You owe me $1800.
