Assemble Bag Body
1. Fold bag unit in half and sew together side edges (Diagram 8). Using tip of iron, carefully press seams open.
2. To shape a flat bottom for bag, at one corner match bottom seam line to side seam line, creating a flattened triangle (Diagram 9). Measure and mark on seam allowance 2-1/2" from point of triangle. Draw a 5"-long line across triangle, and sew on drawn line. Trim excess fabric. Repeat at remaining bottom corner to make bag body. Turn bag body right side out.
