Texas’ Deb Hart shows the start of these petroglyphs on Instagram but how she arrives at the small squares with caned petroglyph images in the middle is still baffling.

They are built into an extruded string outline. Wow, that looks labor-intensive. She’s releasing more photos of her progress on the new inlays as she goes.

Here, she shows a Zuni Bear petroglyph and a coiled snake. Maybe she’s gearing up for a tutorial about her newly developed methods.
