Circuit around the back of the scarf;
1. Download the pattern piece pdf.
SCARF-KITRONIK
2. Cut out the fabric following the pattern piece.
3. Taylor tack through the pattern piece and fabric. (This will be your marks where the LED’S will be placed.)
4. Gently pull the paper pattern piece away from the fabric. (Through the taylor tacks)
5.Place LED’S through the fabric. (tack marks) Once through the fabric, bend out the legs according the circuit plan.
6. Thread up a sewing machine with conductive thread within the bobbin underneath and standard thread through the needle. (on top)
7. Stitch (Straight stitch) line from where the battery will be placed (positive side) to the main (first) LED, leaving thread over at the beginning to hand stitch to the battery.
8. Then stitch from the negative side of the battery to the popper furthest away. (using straight stitch)
Ensure thread is left over at the beginning of the circuit and at the end, in order to hand stitch the battery and poppers to the fabric.
9. Hand stitch the poppers and battery onto the scarf using the thread left over into the correct place. (See plan on pattern piece.) Test to ensure the main circuit works, by pressing the poppers together. (The single light should light up.)
10. Mark out with taylor chalk the stitch lines to follow to join the remaining LEDS to the circuit.
11. The stitch (on a sewing machine, using straight stitch) across each positive and negative sides to join up the parallel lights, with conductive thread.
Ensure that all the positive sides join together and all the negative sides join together. (A positive cannot join with a negative or the circuit will not work.)
12. Test to ensure the circuit works correctly with the additional LEDS attached by joining the poppers together.
(All lights should light up)
13. Cut off all loose threads around the circuit.
Circuit at the end of the scarf;
14. Place the pattern piece onto the bottom end of the scarf and taylor tack through the paper to mark out where each LED and tilt switch will be placed.
15. Gently remove the pattern piece from the fabric.
16. Then using taylor chalk, mark out the circuit following the diagram on the pattern piece.
17. Push through the LEDS where they’ve been marked out and bend open the legs on the other side.
Ensure that the positive legs face the outer edge of the fabric and the negative sides points to the inside of the fabric – (mark out for clarity.)
18. Using a sewing machine (Conductive thread underneath) stitch from the positive battery point for 2cm and then leave a small gap for the switch to be stitched in. Continue to stitch after the gap.
Ensure thread is left at the beginning to attach to the battery.
19. Using a sewing machine (straight) stitch from the negative side of the battery through to where the tilt switches will be placed.
Ensure thread left at the beginning to attach to the battery.
20. Using a sewing machine (straight) stitch across the negative sides of the LEDS across to the off cuts of conductive threads.
21. Then change the sewing machine settings to a zig zag stitch and with random motion, stitch the loose threads to the fabric.
22. Hand stitch in the battery using the thread left (purposefully) at the beginning.
23. Using conductive thread, thread through beads, with a nut hanging at the end of the thread.
The nut will touch the chunk of conductive thread and activate the circuit to light up the LEDS.
24. Hand stitch on the hanging tilt switch (with beads and nuts) into the places marked out with taylor tacks.
25. Cut off any loose threads.
Embellishments;
26. Rip the shear fabric into long strips.
27. Pin on strips across the length of the fabric and then straight stitch (using a sewing machine) across the top of the strip.
Ensure you leave a 1cm gap in between strips. Also ensure that you remove the pins as sewing and that the LED’s can still be seen.
28. After all the strips are secured, clump various different materials together (to fill the gaps) such as yarns and pin down.
29. Then using a needle and thread, hand stitch the clumps of yarns into place using basic tacks.
31. Cut off all loose threads.
Lining;
32. Pin the backing fabric onto the scarf upside down, so that when folded through, the backing material and embellished material are facing the correct way.
33. Using a non conductive material (such as Bondaweb) secure over the conductive track lines, ensuring the positives and negatives can not touch when worn.
34. Using a sewing machine (straight stitch) around the outside of the scarf, leaving one end open at the end to pull the scarf the correct way around. Also, when stitching, ensure a small gap is left open at the battery (end of the scarf) to ensure a switch and a non conductive fastening can be attached.
35. Hand stitch in the switch using conductive thread. Which will complete the circuit at the bottom of the scarf.
36. Using a sewing machine (straight stitch) across the bottom to finish the scarf.
37. Cut off any loose threads.
