1 Start by cutting out fabric pieces, according to these measurements (which include seam allowance): – 84cm x 42cm piece for the main body of the bag
– 2 x 10cm x 50cm pieces for the handle.
2 Fold and press a 2cm hem on both the short ends of your main body piece, stitch down using the sewing machine. These 2 edges will be the opening of your finished bag.
3 Trifold and press the 10cm x 50cm panels along the length. Using a double stitch, sew along the length of the handle. Attach these handles on the hem you just made on the inside of the bag’s main body. These will be your bag handles. Top stitch to secure in place.
4 Fold the main body in half, right sides facing, and pin both sides together. Sew a 1cm seam along each side.
5 To make the square corners of the bag, flatten the base of the bag out. Measure in 5cm from the corner tip and pin through both layers of fabric. Sew a straight line across the corner – your stitch line should follow and go through the 5cm marked position. This will create a triangle shape as shown. The sewn line should be 10cm in length. Repeat on the other side. This will create a 10cm base/gusset to your bag.
6 Once both corners have been sewn, turn bag inside out and use hands to push out the corners neatly. If you want you can stitch the triangle shapes down to the base of the bag or you can cut the excess fabric off and overlock or zigzag the seam allowance. Your bag is now ready for use!
