These step-by-step instructions will show you how to combine fabric buttons, fabric pressure sensors, and conductive fabric traces as well as some funny elements, all in the name of wasting energy for no particular reason.
There are 7 different components to this wearable. And below is a list of the materials and tools you will need to complete them. The following 7 steps will explain how to make each of these components. And the idea is that you come up with your own design and layout for the components, and maybe even add some new elements.

Step 1: Conductive Fabric Traces
Step 2: 9V Battery, Battery Snaps and Little Pocket
To connect the 9V battery snaps to the conductive traces, strip the ends of the wires that come out of the battery snaps and make a little loop. Solder this so that it does not unravel. Use conductive thread to sew the loop onto the end of the fused conductive trace.
You will want to make a pocket for your battery. Best to use stretchy fabric and cut it a bit smaller than the actual size of the battery so that the stretch will keep it in place. Also, make the pocket 2 or 3 cm longer than the battery, this way it stays in nicely, even when upside-down.
Step 3: Fabric Switch

Step 4: Fabric Pressure Sensor
Step 5: Vibration Motor Embedded in Shapelock
Shapelock is a very cool thermoplast. It comes in small pellets and when you pour a handful of them into hot water they will melt and stick together. They are ready to mould when transparent. Take out the cluster of hot plastic pellets and shake off the hot water. Mould into solid form and then form around the small vibration motor, leaving the two soldered loops sticking out. In this example I simply soldered to these rings in order to connect them to the conductive trace, but the idea of embedding the motor in Shapelock is to make it washable (not in hot water though!) and so that the rings can also be stitched to the conductive traces with conductive thread. Getting rid of the wire, which is a good thing, in terms of wearability. I guess.
Step 6: LED
Step 7: Decorative Elements: the Doll and the Sun
Step 8: And That Was That.
I attached the batteries to their snaps and slipped them into the pockets and put on the sweater and pressed the button and the pressure sensor and watched them work and wasted energy all the while I wore it.
