I wonder if they started with a thinner cane and somehow mushed it in and out to make a larger glob but then rounding the mass seems like it would have been pretty tricky - it's a real stumper. Regardless, given the rarity of these types it seems like something not just any craftsman could do - it must have required significant and specialized skill.
@Steph Thanks for the response. Those are my thoughts too. I checked Elizabeth's book @Pinx pretty carefully and didn't see anything about three color MK Cross-throughs. I do know that she checks in here occasionally so maybe she'll be kind enough to share her thoughts the next time she drops in.
FWIW, I have noticed in the past that one cannot attach photos directly to a PM but can insert a link to a photo that is stored at an offsite location or even in a post (or from your attachments directory) here, and the photo will show up in the PM. It is probably designed to prevent users from using the public forum for free "private" storage.
It's really hard to see the seams here, Avaa, but they don't look like MKs to me, unless they are newer ones that I am not familiar with. They look more like Master Cloudy or maybe Akro Moss Agate variants to me.
Only a few older ash trees have survived on my property. I've probably lost 50-75 of them and I've already cut up eight 60-80 footers that fell into the yard or over my access roads this year. The only upside is that I have plenty of good firewood . . .
