Step 3 Transfer your sketch to the garment

Mark up your garment.
Use double-sided tape (or roll single-sided tape back onto itself to create an essentially double-sided tape) to attach your LilyPad pieces to the garment where the sketch says they should be. Be aware of what directions the + and - parts of the pieces should be facing (especially the LEDs - otherwise they won't work!).

Then use chalk or fabric pencils to transfer your sketch to your garment. Be sure to be precise about how your lines look - you'll be sewing over these same lines later on (it's hard to change the path while you're sewing). Also, make sure you match the lines to the holes on the LilyPad pieces - you'll be sewing through those holes later on.

Next, cut out the shapes you want for your conductive fabric. Tape or pin the conductive fabric pieces to your garment. We'll be ironing these on in the next step.

I often find it helpful to attach tape to spots where your traces overlap, so that you remember not to actually overlap the conductive threads. There'll be more instructions on what to do at overlap junctions later in the tutorial in step 7.
