WHAT YOU'LL NEED:
Step 1. Cut two pieces of fabric for the outer and two pieces of fabric for the lining of the pouch each measuring 22cm wide by 19cm high.
Step 2. Cut two pieces of wadding measuring 18cm high by 22cm wide. Fuse wadding to the wrong side of the outer fabrics aligning the base and side edges with the gap in the wadding at the top. This will reduce bulkiness at the zipper.
Step 3. With the right side of one of the outer pieces face up, align the zipper length right side down along the top long edge. Place one of the lining pieces face down aligning all layers together at the top. Pin and then sew together using a zipper foot on your machine close to the teeth of the zipper.
Step 4. Repeat step 2 for the other side of the zipper and with remaining fabric pieces.
Step 5. Pull fabric right way out away from zipper and press flat. If desired top stitch fabric 3-5mm in from zipper edge.
Step 6. Up-zip the zipper half way and with right sides facing pin the two outer fabric together aligning all remaining edges. Repeat with the lining fabrics and pin together. Pin the teeth of the zipper towards the lining side.
Step 7. With a 1cm seam allowance sew around all of the pinned edges leaving a 5cm opening at the middle base of the lining side. Trim wadding in seam allowance back to stitching. Clip corners and pressed seams open at corners and base.
Step 8. To create boxed based corners, pinch out each corner to form a triangle with the seams running down through the center of the triangle. Using a pencil and ruler, draw a line for the base of the triangle 6cm long 3cm on each side of the center seam. Sew across the line and trim away wadding to seam stitching then excess fabric leaving a 1cm seam allowance.
Step 9. Turn out pouch through the opening in the lining. Press in the seam allowance along the opening and top stitch closed. Place lining back inside the outer pouch and push out each corner and press.
