That's some lovely work and ideas.
As I've been dealing with my declining vision, I've been thinking about perceptions and the ways different people experience things. One of my ideas for quilting is to do a "braille" quilt, no not textural, but talking the elements of braille letters and making blocks spelling out a message that basically only I would know or understand. To the rest of the world it would just be big bold graphic shapes, most people would probably sense some sort of dice shape in there.
The other day someone had a thread about using different fabrics and I was thinking to myself maybe adding in a textural element for the raised parts of the letters, but it would be at a scale only read by giants!
