Step 4 Cut the Clear Plastic Film

Cut off the zip top of the 1 quart sandwich bag.

1.  Make the cut 5 inches from the bottom of the bag.  
This will create a 10 inch long  Clear Film Blank when the bag is unfolded in the next step. 


2. Cut down the two side seams of the bag (photo 2) to allow the bag to unfold open (photo 3)


Note: A quart sized bag width is comparable to the width of the White Film Blank cut earlier.  
Again, the final dimensions of both the White Film Blank and Clear Film Blank should be smaller than a letter sheet of paper to avoid the plastic from coming in direct contact with the hot iron.
