Now sew the whammy bar and the input jack. Take three strips of bias tape (or any fabric that matches the color of your scratchplate). Their length should be the same as your whammy bar. These strips would be your single-coil pickups. Position them according to the image and sew. Mark the parts of the scratchplate where the screws are. Embroider these with silver thread. Handsew circles on the strips you just added. Remember,these circles should be aligned.
