Been having a ton of fun playing with block themes, learning new stuff every day.
For the last week or so I've been working on a new theme that I've called Lumen, and I just activated an early version on my site.

Block Theme Cheat Sheet for WordPress
I Made a Cheat Sheet for FSE Block Themes (So You Don't Have to Reinvent the Wheel) Here's the thing about developing with Full Site Editing block themes: you're constantly looking stuff up. What blocks are available in core? What goes in theme.json? Which hook was it that fixes that one annoying thing? I've been building FSE block themes for a few years now, and I kept finding myself Googling the same things over and over.

Diving back into the #WordPress Developer Blog with a short but useful snippet: Limiting allowed blocks without breaking the Site Editor developer.wordpress.org/news/snippet...
Snippet: Limiting allowed blocks without breaking the Site Editor
Avoid breaking the Site Editor when limiting blocks. Scope the allowed_block_types_all filter by context to keep flexibility for designers and focus for editors.

So this little thing called #WCEH happened. After 13 months of planning (and a few weeks to recover 😅), I wrote about what it was like being an organizer. Hoping it inspires others to get involved—it’s worth it.

Been quite a while since I’ve done any sketching. Took a break from coding and grabbed my iPad and sat outside while the kids rode their bikes.
