- Starting at a straight edge of the main body piece. Place a side piece under a piping edge.
- Stitch on the piping attachment stitching line. As you approach the curve of the side piece, stop and snip the seam allowance of the body piece.
- Continue attaching the side to the body until you reach the end of the side piece.
- Repeat for the second side.
- Note: It may be necessary to trim the top edge of the flap to meet the side piece if you haven't stayed perfectly on the allowed seam allowance. This does not affect the way the case fits but DO trim to create a smooth edge for attaching the bias tape.
- Press the seams in on the side seam. This will add strength to the sides of the case.
