Print out the pdf file and cut out (either you choose the pre-printed templates or you color the black&white templates as you like)
Cut the cardboard roll into two (or chose any other height) and using a needle feed a string through opposite sides of the upper part of the rolls so that you can later hang the rolls onto the branch
Glue the cut out motifs to the rolls (you may either glue the same motifs to one roll or vary and mix the individual motifs)
Hang the complete decorated rolls on the branch or make them into a colourful mobile
