It is dangerous to use a thin board as an inclined plane because the board could break, splinter, or collapse.
A wedge is a modified inclined plane that is thick at one end and tapers to a thin edge at the other. It functions by converting a force applied parallel to the thick end into a force perpendicular to the thin edge, allowing it to split objects apart.

I think you are allowed knitting needles in your luggage that goes into the plane hold (main luggage), but you are not allowed them in your hand luggage because they can be classed as dangerous.

The thin set under the board is to fill in any low spots in the floor. It is not to adhere the board to the floor. It is preventative against deflection. If there is a low spot and you do not fill it in, the board will flex and the grout/ tile will crack. Do not use construction adhesive it will do more harm then good.
