Hello minkiehuoise,

As you probably know I am also a dope and fabric guy for good reasons.

I can only tell you how I proceed for the hinges.

It is quite obvious that the hinges would interfere with wrapping the fabic around any location. We do not want them there when covering.

One thing I do is write a note on paper of the diminsions to each side of the slots or of the center from a reference point. After the last coat of butyrate it is usually easy to see the slots through the clear butyrate before using any color. I then make a cut of the covering for the length of the slot (approximate width of the hinges).

Then after using the colored dope it is easy to find those slots in the fabric.

With a sharp #11 Xacto blade it is easy to trim the fabric slots to the width of the slots (thickness of the hinges) as the fabric is now easy to trim being in cured dope.

Voila

I also have my own way of using 30 min epoxy to avoid having epoxy at the hinge line (hinge pin).
Of course I do not use CA hinges; only pinned hinges. The control surfaces have to fall more then their intended deflection by their own weight before being connected to their servos.

I am writing what I do and I am not telling anyone what to do. It is for each to evaluate what is best in their opinions.
