Next we will cut the medium/light strips sets – please note they are a different angle so read and check photos before cutting. Notice the colors are similar but the outside green is lighter than the prior post.  This is my medium strip set.

Here is the photo to make your initial angle on the medium strips.  You will then make your angled cuts.   Notice on photo that the ruler and corner piece is cut from the top this time, not the bottom of the strip.  It matters. 

You will line up the 2.5 inch mark on ruler as with the dark and cut along the far left hand edge of the ruler to create an angle on the top left corner.  Then the angled strips will be cut 2.5 as well, just like the dark.
