Never too old?

       I'm about three weeks shy of 83 and today learnt another term I'd never heard of. 
       I do NOT claim to be omniscient by any means - BUT - am still amazed at learning new stuff.  It's not many months since I had to search when I saw "colorography" and thought it was a mistyped Calligraphy. 
       This time I didn't mistake "Stumpwork Embroidery" for anything, I just didn't know it was:- 
"What is stumpwork?
Stumpwork or raised embroidery, is a technique that became popular in the 1600s.  The idea is to use different stitches and techniques to create raised surfaces".  
       The Event organiser, Clicky Chick, suggested a visit to Rheged where there was an exhibition "In Bud & Bloom exhibition opens at Rheged."  Not possible to assign a genre; there were Paintings, Photos, Wrought Iron, "all-sorts".  
       Thoroughly enjoyable - BUT - we came away with searches in mind.  We'd heard of "Cyanotype" but were ignorant of the full "meaning" and we'd not come across Stumpwork before.
       If you're as unlearned as I/we were on cyanotype it's here:-
"The cyanotype is a slow-reacting, photographic printing formulation sensitive to a limited near ultraviolet and blue light spectrum, the range 300 nm to 400 nm known as UVA radiation. It produces a monochrome, blue coloured print on a range of supports, often used for art, and for reprography in the form of blueprints."  I suppose the blue is responsible for the "Cyan" part of the name?
