      flaps with rounded edges for closure.

   View A of the sleeve; see the gallery below for a picture of view B.

A simple neoprene sleeve to protect laptops while carrying them inside
bags, backpacks, etc in two views: A with rounded corners, and B
with straight corners for laptops that are especially pointy.

It can be sewn by hand or by machine; view B has tight corners and
sewing it by hand is recommended.

Materials
---------

Fabric
^^^^^^

* A piece of neoprene about as wide as the laptop and a bit more than
  twice as high.

Notions
^^^^^^^

* Strong polyester sewing thread, such as the same one used in the
  :doc:`../../bags/modular_backpack_base/index`.
* elastic edge binding braid, about 2.5 times the width of the laptop;
* regular sewing polyester thread that matches the braid.

Pattern
-------

Measure snugly around the thickest part of the laptop both horizontally
and vertically.

Get the valentina pattern :download:`laptop_sleeve.val` and enter the
measurements in the Variables Table.

Alternatively, for view A you can draw three rectangles: the base is
half the circumference measurements, the top and bottom front are as
wide as the base and 1/3 and 2/3 its height plus 3 cm respectively.
Round all corners with a radius of 4 cm.

For view B, make just one rectangle, as big as the three rectangles
above, and round its corners with the same radius.

You can also download an example pre-rendered pattern of view A for the
Thinkpad X200, whose circumference measurements are 47 cm vertically and
65 cm horizontally.

Instructions
------------

All structural seams are done with strong thread by abutting the two
neoprene parts and either using a wide zig-zag stitch on the machine or
with an herringbone stitch on both sides of the fabric if sewing by
hand.

View A
^^^^^^

   :align: center

Cut parts A, B and C of the pattern in the neoprene.

Carefully align part C to the side of part A and sew the side, bottom
and other side, starting and ending just below the rounded corner of
part C. Push the neoprene to keep it aligned when going around the
corners.

Do the same to part B, sewing the side, top and other side to the base
A.

View B
^^^^^^

Fold up the bottom part of the neoprene on the marked line, sew the
sides starting from the bottom and going up until just below the rounded
corner.

Do the same to the top part of the neoprene.

Both views: edge binding
^^^^^^^^^^^^^^^^^^^^^^^^

Starting from the center of the bottom flap, cover the raw neoprene edge
with binding braid and either topstitch it down by machine or,
recommended for best results, whipstitch it by hand on both sides, using
regular sewing thread in either case and going carefully around the
corners where the flaps and base meet.
