proprioception/propriocentric feedback

We are all interested in feedback but proprioception is a form you can only give yourself. I was in conversation earlier with Rob Lee of Lee Valley/Veritas Tools about chisel length and he brought up the term, propriocentric feedback... the sense of one's body parts position relative to other body parts.... The following is from Wikipedia...Proprioception
(pronounced /ˌproʊpri.ɵˈsɛpʃən/ PRO-pree-o-SEP-shən), from Latin proprius, meaning "one's own" and perception) is the sense of the relative position of neighbouring parts of the body. Unlike the six exteroceptive senses (sight, taste, smell, touch, hearing, and balance) by which we perceive the outside world, and interoceptive senses, by which we perceive the pain and movement of internal organs, proprioception is a third distinct sensory modality that provides feedback solely on the status of the body internally. It is the sense that indicates whether the body is moving with required effort, as well as where the various parts of the body are located in relation to each other.
Sir Charles Bell, who wrote the book about the Hand, used the term muscle sense and I suspect you would have to be interested in the human hand and body for any of this to be meaningful to you.

Today in the CSS wood shop, 4th, 5th and 6th grade students worked on their hand-made journals, and began making game boards to use in their travels. The Fox and Geese game boards are based on those featured in A.J. Hamler's new book on Civil War Woodworking projects. Our high school students started work on an Ark of the Covenant as part of their world religions class.

Scrapwood Bob sent this link to a yurt building/spoon and bowl carving class with Bill Coperthwaite, so while I neglected to get any photos taken today while in the CSS woodshop, I'll share these above and below from Bill Coperthwaite's yurt building workshop with CSS students in 2002.
