To create the upper and lower speaker cone, position and stick pieces down onto white duct tape (leave a 1/8'' gap to create a hinge). Cover the whole side in duct tape and trim the edges so that it's flush around the plastic.

Flip over and apply blue duct tape to the entire other side and trim to 1/4'' away from the plastic. Fold the blue tape over on the curved edge only. Leave the rest exposed as this is what attaches the cones to the booklet.
