Cutting out the Pattern The parts to this duffle bag are very simple to cut out by diagram made from canvas or denim weight fabric, it will likely not need interlining if the fabric is soft or has long "floater threads" on the back, it will be a good idea to interline it . When you interline something an identical piece is cut from lining fabric and place wrong side to wrong side with the fashion fabric, then both pieces are treated as a single piece.
End piece- Cut two fashion fabric, optional cut two lining fabric if you do not have a compass to draft the circle you can use a string that has been pinned to the center of the paper and marked at 4 ½ inches.
BUT double check to make sure it is 9 inches when it prints out
Main Bag Piece Cut one Fashion Fabric, optional cut one lining fabric
Strap/Handle Pieces Cut two fashion fabric and optional cut two lining/interlining fabric these you may want a bit firmer than just your lining.
