Step 4: Glue LilyPad pieces and iron conductive fabric onto your garment
Trim the leads off your power supply.
On the back of your power supply, there are metal parts sticking out. Trim those off with scissors or pliers (shown in picture below).
Glue the taped LilyPad pieces on.
Once you've figured out where you want your LilyPad pieces, choose a piece and remove the tape. Using fabric glue (or some non-permanent glue), attach the LilyPad piece to your garment. Again, in this step, be certain to orient the + and - ends of the pieces in the correct directions, and make sure the holes on your LilyPad pieces match up to your chalk traces. Repeat until you have glued down all your LilyPad pieces in the correct positions.
Iron the conductive fabric onto your garment.
Your conductive fabric should now be pinned or taped onto your garment. With an iron turned to a medium setting with no steam, iron the fabric into place. If the fabric wrinkles, heat it up again with the iron, and rearrange it so that it is straight. If you happen to iron something in the wrong place, heat up the fabric in order to straight or move it. Be careful! The conductive fabric will be VERY hot!
Be sure to let the conductive fabric cool before trying to move the garment - while the fabric is still hot, the adhesive has not yet solidified and so the conductive fabric is not yet entirely stuck.
