Quick and easy project =) I would maybe use a thicker foam sheets to give it more depth, but I only got the 2mm one at my local art store and it was super cheap for like 20 foam sheets. Think I payed under 5 euro.
But some materials you will need are:
-paper (i printed on 200gsm but I think you could get away with printing on normal printing paper)
-foam sheets (I used 2mm)
-sticky foam squeres
-glue or double sided tape
-uhu all purpose glue for the foam
