Sandwich the pant leg between the two pieces of an embroidery hoop. If your solid piece has a "grip lip," make sure it is facing up.

Begin tightening the knob on the outer ring and also pulling the fabric taut in the hoop.
Place your FLORA main board and single pixel on the taut fabric, and sketch out your pattern (or trace ours) with tailor's chalk.

Thread a needle with 2-ply conductive thread and pierce the fabric from back to front next to the pad marked D6 on FLORA.

Leave a 5" tail at the back of the fabric and make a few stitches through the D6 hole, securing it to the pant leg.
End at the back and tie a knot with the working thread and the tail you left at the start. Seal the knot with clear nail polish or fray check.

Use a running stitch to sew a path with the working thread up the angler's lure to the end. Make a few stitches around the pixel's pad marked with an inward-facing arrow to secure it both electrically and mechanically. make a knot at the back, seal and snip off the tail.
Repeat to make a connection from VBATT on FLORA to + on the pixel, and likewise from GND to -. You will now have three independant paths sewn from the main board to the pixel.
To make the fin, sew one half of a snap to a small piece of fabric with conductive thread.

Knot and seal at the back, then cover the snap by folding the fabric in half.

Stitch two lines as shown in plan thread, creating the shape of a fin. Cut off excess fabric about 1/4" from the seam and turn the fin right side out.

You should have a long piece of conductive thread coming from the inside of the fin.
Stitch the other half of the snap to the body of the fish (on your shorts) with conductive thread and use a running stitch to connect it to a pad marked GND on FLORA.

Line up the snap on the fin and snap together, then stitch the fin to the body with plain thread.

Pick up the conductive thread tail coming out of the fin and use it to stitch a path to TX (aka D1, or any digital pin) on FLORA.

These two parts will serve as a switch, detectable when you snap and unsnap the fin.
Double check your circuit for stray threads, and get ready to load it with a program that will change the lure's color when you snap the fish's fin.
