To get started, you'll need to set up your sewing machine with the thread you want to use, and plug in the iron. Next, measure out the two pieces of fabric you're going to need to put together your Santa sack.
I chose to work with some leftover linen, and I cut it into two 20" x 26" rectangles.
I folded one of the shorter sides on each piece of linen half-an-inch down and then pressed it in place with the iron. Pressing creates a nice, crisp edge, which will make future steps much easier to accomplish.
