You will receive the wall decals without transfer printed on one or more sheets.
Open the packaging and remove the sheets. Spread them out on a flat surface near your desired location of application.
Start with a clean, dry and non-textured wall or surface.
Peel the first decal from the sheet. It should peel easily from the liner.
Place it where you wish and make sure it sticks properly to the surface.
If handling a large design, peel only at the tip of the liner, stick the peeled part first before removing the rest of it.
Slowly smooth the design from top to bottom, pressing down firmly using the card you received,
Ensure that the entire decal makes contact with the wall or surface.
Rub the decal gently from one side to the other pressing any air bubbles out.

If in doubt, you can always consider recruiting a second person to hold the opposite end of your decal to avoid sides sticking together.
Repeat these steps until you have applied all included wall decals.

Et Voila, you’re done ;)
