Place your fabric in the embroidery hoop and then cut off the excess.

Step 3: Sew your electronics

Sew your electronics into the back of the fabric so they don't show on the front. You'll want your LED to be face-down on the fabric, and you'll want to securely attach both the LED and the battery holder to the fabric using the conductive thread (the silver thread). Once both pieces are secured, sew a trail from one of the positives on the battery holder to the positive on your LED. Sew another trail from one of the negatives on your battery holder to the negative on your LED.

The positive trail and the negative trail shouldn't cross or touch each other. However, it's ok if normal (non-conductive) thread touches or crosses these paths. Since your LED will be face-down, make sure you take a good look at which side is your positive and which side is your negative before you attach it to the fabric. 

Once you have finished sewing this part, you can pop in the battery and check that your LED lights up.

Step 4: Cut your felt

You'll need to cut out six pieces total: the main part of the Tardis, the top of the Tardis, the black "Police Box" rectangle, two windows,  and a white square or rectangle (this is where your LED will shine through). While you can make your Tardis however you want to make it, I chose to make the bottom a bit rounded so it would go better with the shape of the hoop. If you decide to do this, your windows will also need to be a bit round.
