here is my piece for 'architexture' ....
 lumen  is a three dimensional hand stitched textile piece with layers of sari  silk, hand dyed machine stitched cotton and sinemay. it was stitched  with cotton and silk thread using sorbello stitch, running stitch and  french knots. inside the piece are 'sticks' i made of cotton string  soaked in black gesso and paverpol.
i  had lots of ideas for this challenge mostly to do with cathedrals,  skylines and gargoyles. but none of them fired my imagination until last  week when i was surfing around the internet and got into a cross  referencing spiral around the theme of liminal space and thresholds  (which was another image i was toying with). there was a link to the  word 'lumen' which of course, Alice-like, I followed and found the  anatomical meaning of the word.
A lumen (Lat. lūmen, an opening or light) (pl. lumina) in biology is the inside space of a tubular structure, such as an artery or intestine.
which made me think of Kind Dog's 'heart event' as the hospital people  called it, which happened nearly six months ago. of the inside of his  arteries and how they were stitched back together lined with mesh. and  how this has certainly saved and extended his life.
so while this is not an orthodox interpretation of the architexture  theme it is certainly of a structure, a space, a construction. 
it is lumen
