A4 Template: Blue | Red | Pink | Orange
Instructions: None. I know you're going to get angry with me when you see how confusing I made the assembly for this. But alternating tabs made it fit nicely together even with half-a**ed scoring and cutting (Look ma, no ruler!). I do have numbered marks telling where you should glue some of the tabs.
And for non-paper Halloween decoration, here is the spider that took me a month to make. Please excuse my mother's noob skillz in web placement. Now random passersby are taking their picture at our house's gate. :)
PS. Red in printer is still dead. Canon people if you're reading this, please send me a printer so I can make more papercrafts. :D
