Hello everyone.

I have a problem.
I work in a magazine store and lately they received some magazines that came fixed on cardboard (magazines that come with parts to assemble cars, ships or miniatures of characters from films or drawings), and some buyers do not want to take the cardboard, so I have kept it here to use.
I would like to use this cardboard to assemble cardmodels, but these cardboard are 1.3 mm thick.
You would have some idea of how I can assemble the model using this cardboard, because after I paste the sheet with the drawing of the model's support, the cardboard will have approximately 1.4 mm.
Since the cardboard indicated is 1mm, I have 0.3 to spare, without the glued sheet.

Any idea how I can go about reducing the thickness.

Thank you and regards to all.
