These I found online with instructions. I forgot to bookmark the page so I cannot find it now. I think they are in *.gif files & they are not to scale when printed. I am a computer draftsman & I am working on an AutoCAD file version which I can print to Adobe PDF at a 1"=1" scale. Though they will not be exactly the same, due to the fact that I am drawing them symmetrically by hand.

The thing I do not understand are the notches in all of the corners of each piece. I know the Gay line should be the stitch line & the black line the cut line.
