Step 1: Materials
The main material you need is the:
A4 water color paper (preferably, if not any paper is fine)
Cutting Mat (you really don't want to cut it on your carpet...)
Scissor or knife (which ever you prefer)
Step 2: Let's Start!
fold the paper in 3 equal section
Step 3: Let's Draw!
draw the pattern something like that... you can do what ever patterns you like, such as like trees, fish, waves etc..~ the whole point is just draw them in layers.
Draw out the pattern you like
Cut the patterns with your cutting tool
Step 6: That's It!
layering each piece on top of each other and you are DONE!
