I made Paper theater this year too.
The front side was open in last year's paper theater. However, this year's paper theater is a complete blockage type.
An internal structure is composed of two rooms.
There is the woods and the background of the sky in the interior.
When light enters it from the ceiling from among the room, the interior became more beautiful.
A warm room of the paper theater looks better when the environmental lighting is darkened.
The secret where it looks warm it in the room is this penlite. ;)
Have a fun ;)
