flatter and noticeably dimmer than the front. Be
careful to place the LEDs front side up.
To attach the matrix to your mesh pillowcase,
you’ll use the double-wire twist ties. Don’t use
standard twist ties — they’ll twist around and
poke through your pillowcase. Using wire cutters
or flush cutters, cut about 50 of the 10cm ties into
approximately equal fourths about 2.5cm long
(Figure
I
). Then, take the input end of the LED
string and lay it along one of the border grid lines,
aligning the LEDs with the intersections.
You’ll secure the LED string to the mesh case
at regular intervals by wrapping it in a cut twist tie
near one side of each LED. Don’t tie both sides of
the LEDs because there must be enough slack to
run part of the string underneath itself. Slide a cut
twist tie through two adjacent holes which border
the Sharpie line so that the tie is perpendicular
to the string (Figure
J
). The tie is slightly wider
than the holes, so you may have to pull the mesh
taut and wiggle it a bit to slip it through.
Using pliers, sharply fold about one-quarter
of the tie over the LED string (Figure
K
), then
fold the opposite side of the tie extending from
underneath the LED string to cover the first
folded section (Figure
L
). With the pliers, bend
and crease the remaining overhanging twist
tie section back underneath the string and tie,
pressing it firmly to grip the wires inside. Tuck
the final short segment into the mesh under the
string (Figure
M
).
Proceed this way down the entire first row,
placing one twist tie just before each LED (Figure
N
on the following page
). At the end of the row,
bend the string into a U-shaped turn and place
the next LED in the closest adjacent row so that it
is offset by one column from the previous LED
(Figure
O
). Proceed to fill all the rows using this
technique until half the LED string is attached to
the case in a zig-zag pattern with one folded twist
tie near each LED. The LEDs should sit at
