Print a blackboard newspaper with gouache

1. Clean the blackboard with clean water to remove oil stains.

2, use chalk to type the manuscript, if you pay attention, you can use white powder as the bottom material.

3, draw patterns, not too thick, try to reduce the number of repeated brush, so as not to affect the picture quality.

If you want to keep it for a long time, after the gouache is dry, you can dilute it with water-soluble transparent glue and cover it with a thin layer.
