Cutting the cardboard

find your way on the cardboard with a mechanical pencil

Cut a cardboard in x / y format and check that its four corners are square.
Mark the first of a cross and always leave it to take the measurements.
If the cardboard plate is new, make the first cut using an edge.
If it is a fall, check its squareness beforehand.

Cut out the cardboard to make a master key

Never draw pencil cuts, but make simple cutter notches as markers.
Position the ruler along these notches, keep it in place perpendicular to the body and cut several times, ensuring that the blade of the cutter follows the rule.
If, when grinding the cut, the dimensions are smaller than expected, it is always possible to reduce the margin by 1 or 2 mm.

Marginization of margins

marking margins on the cardboard

On the side of the cardboard (right for the right-handed or left-handed for the left-handed), note with a simple pencil mark the measure of the margin with the help of the rule (here: 6 cm).

frame: use of the pencil compass

Open the pencil compass at this measurement and extend this margin on all four sides of the cardboard.

Opening the master key

open master window

Open the master window with a new blade cutter.
Position the ruler, perpendicular to the body, on the part to be guarded (here the margin), then from a corner of the window and pull the cutter towards you to the next corner.
The cut must be frank.

Sticking the cardboard

wet cardboard with a sponge

If the mat is laminated or cardboard micro flutes, go directly to the next step.
In this case, the mat is a cardboard, it will be covered with paper.
Cut the paper directly to the cutter, freehand, counting all around about 1 cm more than the cardboard.
Then, if necessary, wet it upside down with a wet sponge.

applying the glue with a flat brush on the window of the passe-partout

Without further delay, glue the place of the cardboard (that is to say the side on which there are no lines) with a flat brush on a cardboard provided for this purpose.

apply glue to the mat window using a roller

Be sure to spread the glue over the entire surface, especially on the edges of the window and smooth it with the roller.

stick some paper on the cardboard

Place the glued cardboard on the work surface and arrange the paper on it, slowly applying it from bottom to top.
Marouflage with the fingertips to remove any bubbles and help the paper to stick well on all sides.

Tips for gluing

  • Work with clean fingers because the vinyl glue stains.
  • Never use the cloth to rub the paperwork or wipe off the glue stains, as it may transport or spread it.
  • You have to trust your fingers, we feel good if they tie.
  • Finally, if you make a stain of glue on a conventional paper, wash quickly with a damp sponge. On fancy paper, more fragile, the stain will unfortunately be apparent.

Opening the window in the paper

cutting the paper with a cutter

Flip the work to open the window in the paper by pointing the cutter well in each corner and cutting in the middle about 2 cm.
Hollow out the central rectangle freehand.

glue the back of the cardboard with a brush

Glue the back of the cardboard with a paintbrush about 2 cm, near the window and to the corners, then back the paper by pulling well, especially in the corners so that it marries the window.
Then cut the paper that is all around, flush with the cardboard.
