I normally don’t post my art (mosaics, stained glass and watercolor). But this piece was made for my husband who is visually impaired. This is a mosaic tactile piece called “Looking Up”. He loves touching redwoods so now he can go get a feel of glass bark, when we are not actually in a forest.

Not all seeds have endosperm as their storage tissue. Some seeds store the energy needed for germination in the embryo’s cotyledons. You know peanuts: the 2 halves are the 2 cotyledons. The embryonic root & shoot are the little structures at the base. #cotyledon #Fabaceae #Botany 🌾🧪🌱

When I visited the bristlecones I was amazed at the view. Good place to spend 5,000 years.

#InkTober2025 Day 8: Reckless.
Was planning to draw an eloborate scene from the time when birds ate horses. But it was one of those days and I’m glad I at least got this guy on paper, Terrorbird Titanis walleri. Based on Blue Rhino Studio’s amazing diorama, brushpen with Copic markers.
