Step 2
Instructions
(a) Print and cut out the side section. We are going to use this as a template to make 4 black side sections. A penknife is recommended to cut out the slits of the side section.
(b) Trace out the side section template on a piece of black coloured paper. We gonna need four of these.
ps : black is used for the side sections because its gonna emphasize the contrast of the animation strip
Materials
2 x A4 black colored paper
side section printout
