Grab a needle and test it's small enough to pass through the holes in the sequins. Thread up your needle with conductive thread, our 2-ply and 3-ply both are great for this purpose. Check out our conductive thread guide to learn more about this stainless steel fiber.
We find it easiest to load up your fabric in an embroidery hoop to keep it taught during stitching, especially for beginners.

Begin by piercing the needle through the fabric from back to front, near the + on the pixel leaving a six-inch thread tail at the back. Then affix the pixel to the fabric by piercing the needle down through the hole marked + and through to the back of the fabric. Repeat to make a few stitches around the pixel's + connection.
Avoid using pin D1 when using the Gemma M0. Instead use three LEDs in parallel on using pins D0 and D2.
Stitch over to a digital or analog output on your microcontroller, and repeat the stitching process around the circuit board's pad.
Stitch back over to your thread tail at the back and tie the two threads in a double knot.

Seal the knot from springing loose with some clear nail polish or other adhesive.

Snip the thread tails short.
