This section was bolted back on before laying up, and due to the shape of the undercut and to avoid any issues with bridging or pulling the weave, I laid up the small section before bolting it back on. Did this by applying strips of Airtech Airhold to the carbon fibre so I could cut it to shape without fraying. Once it was laid down, I noted with a marker which direction the weaves were going. Then when I laid the first layer for the rest of the top skin, I simply matched the weave direction and then I could snip it to allow me to push it into that undercut without pulling the weaves, whilst hiding the cut edges behind the split section.
