When replacing insignia and collar tabs to uniforms, what is the best way to do it?
Is it best to hand sew the collar tabs or machine sew them? With the collars tabs, it doesn matter that the thread goes right through, unlike the eagle with jacket lining?

Is there a certain way items should be hand sewn?

Also does anyone know if its possible to get original cotton thread, or would new cotton be ok? Will new cotton glow?

Any other tips or help when restoring badges etc would be great.

Look forward to your views and opinions, thanks!
