Am working on a Spinning Spools Pattern, called Teepee Sunrise. It came with almost all of the templates pre-printed on template plastic. However the largest piece was not. it is a large triangle that is 6" x 12" and then they state add seam allowances. now I know this is splitting hairs but do you measure the 6 x 12 then add the 1/2 inch (quarter for both sides) or do you measure 6-1/2 x 12-1/2 to begin with. Believe it or not you get two different angles.....this is a link to a current listing for the pattern....
