Also, this continued video quality issue is the main reason I find myself going back to IG. @bsky.app :/

This piece is called “Deer Resistant My Ass!” We have a few painted rocks around our garden. After deer browsed my evening primrose literally the day I planted it, I thought about a rock with this quote. Then was like “wait. I have a bandsaw.” #nativeplants #starwars #failure Oenothera biennis

I found a dead fly in my yard. Turns out it’s zombie fly infected with a fungus that makes it find a high perch, spread its legs/wings, die, and release fungal spores below. I’ve found 3 now, with 1 shipped to @zombiflied.bsky.social at Harvard for science! Just in time for Last of Us finale! 😂

After 87 years, zebra swallowtail butterflies return to Pittsburgh thanks to pawpaws
Although its host plant is native to Pittsburgh, no sightings of zebra swallowtail butterflies had been reported in 87 years. Until now.

It happened! At least 4 of the 32 zebra swallowtail #butterfly chrysalises that overwintered survived (maybe all). The 1st eclosed today! This shot was NOT planned. 3 more coming in the next 1-2 days. All offspring of this single mom: www.publicsource.org/zebra-swallo... #pawpaw #nativeplants

Another tiny strip of lawn I’ll never mow again! The other side is neighbor‘s lawn. Shrubby St. John’s wort + foxglove beardtongue from seed. I’ve solarized w/cardboard/mulch around plantings before. Works well enough. If the deer strike and I need to replace, well the hard part’s done.

Just perusing through your native plant photos. :) this one reminded me of some NE aster shots I took this week! Yes, really. I grew them from seed under light in my basement. Then took them in and out trying to harden them while avoiding freezes. They’re so confused 😵‍💫 😂. I was shocked.

Made a new #hobbit hole for our front garden. Partly to make kids/parents smile when they walk by. But mainly to make myself smile. Scrap fence cedar and acrylic paint. It’ll look better with real plants around it I think. Pieces cut on #scrollsaw. #woodworking #geekart

Cold & rain makes for a great day to do my annual refinish of this inlayed patio sunflower table I made. Downside of oil-finish: yearly maintenance. Upside: it’s easy and much prettier than something like spar urethane. It stays on our porch so at least somewhat limited exposure to elements.

Purely based on my 1 successful attempt at doing exactly this: don’t give up hope on them if it takes FOREVER for them to pop out. Haha. Mine took like a couple months to germinate (I tried scar vs non-scar, fridge cold strat vs fall sow). But everything ended up growing after a few months.

Next 2 stages of glue up. Since body is glued, I 1st did the bottom wing, pressing them toward center with cauls. Then repeated with forewings. You can see the cauls (a superglued scrap and a wedge) in the second photo to apply clamping force. The pieces interlock at the body creating a pivot point.

1 step of glue up has begun. I usually find it helpful to glue at least 1 piece to serve as a stable reference when I go to glue the rest. Tiny errors are additive (especially with over 300 individual pieces of wood). So it’s best to take it in stages. I’ve never had a stress-free glue up. 😂

Demonstration of homemade iron acetate (vinegar+0000 steel wool) stain. I’ve had this stuff sitting in the shop for a year+ with no loss of potency. After the steel wool mostly dissolves, I run it through a tshirt or coffee filter. Some maple turns shades of gray. Walnut and red oak turn black.

1 way I make my #woodworking more sustainable is by ebonizing common woods like this black walnut instead of using e.g. ebony. Vinegar + steel wool in an old mason jar = iron acetate (& hydrogen, so don’t seal it💥!). The solution reacts with tannin to create various shades (depending on species)

I started many of my #nativeplants seeds suuuper early (like December), mostly as a mental health exercise, and expecting failure. But so far like 95% of it still looks happy and healthy-ish. For a cool dry basement under cheap lights anyway. The main challenge has been fighting the fungus gnats.
