 careful not to sew the ribbon. Place the top flap centered on the top
 side of the lining, and sew also the top edge 1 cm from it.

+miter the corners.
 
+Turn the bias tape towards the inside, whipstitch it in place by hand.

+Flat needle slots
+^^^^^^^^^^^^^^^^^
+
+Instead of making box pleats at the bottom of the needle rolls you can
+make the base and needle holder the same size, and sew the bottom flat.
+
+In this case, the python code to calculate the width of the slots
+becomes::
+
+   > sizes = (
+         2.00, 2.25, 2.50, 2.75,
+         3.00, 3.25, 3.50, 3.75,
+         4.00, 4.50, 5.00
+     )
+
+   > [math.ceil(s * 6 / 5) * 5 for s in sizes]
+
+   [15, 15, 15, 20, 20, 20, 25, 25, 25, 30, 30]
+
+   > sum([math.ceil(s * 6 / 5) * 5 for s in sizes]) + 30
+
+   270
+
+and in this example for a set of 13 cm DPNs the fabric to cut would be:
+
+* base: cut 1 in fabric and 1 in lining, 27 cm × 17 cm;
+* needle holder: cut 1 in lining, 27 cm × 26 cm;
+* flap: cut 1 in lining, 24 * 12.
+
+When assembling, you can then mark the channels just on the needle
+holder, pin it in place aligned to the base at the bottom and short
+sides, and sew all the channels at the same time.
+
+Everything else remains the same.
