"shores"

Our neighbours Herb and Fannie were over for a visit this afternoon.  I showed Herb the burlap flake that I made.  He introduced me another vernacular word "shore", or "to shore".   "Shores" are the posts, supports of the flake structure, or any building structures.  It is also used as a verb, "shore" up the longer (a long pole used to make the platform of a flake).  Herb said he would show me how to put the shores up to the longer.  I will go to see him in the next few days.
