Step 4: Sewing together the plastic bags

Picture of Sewing together the plastic bags
Start by "truing" up the pieces, trimming the edges so they are all straight and even.

Position the pieces to make a rectangle big enough to fit your computer on it twice, with a bit extra for a closure flap. Keep about 2 1/2 in on each side for seam allowance.

Sew pieces together by overlapping them on top of each other and sewing with a zig zag stitch
