The first step is to cut your sheet music into 1"wide by 4" long strips. I did not count how many strips I needed for the tree, I just estimated, and then cut more as I needed them. I think you will be surprised how many strips you will need. I used my rotary cutter with a
pinking sheers blade, a self-healing mat, and a straight edge. However if you do not have these tools, a pinking sheers scissors would work just fine. Other versions of this tree can be made with plain scissors, or by even folding and tearing the sheets of music to create a soft edge.
For the sake of time I cut all my strips 1" wide, and then went back and cut them into 4" lengths.
