1. Painting using this Goose Neck paintbrush is the way of the Slytherin.
One of the traits associated with Slytherins is cunning. Judging based on the way this regular looking paintbrush cunningly bends to any direction and can be screwed onto an extension pole for painting high and difficult angles, it is also one of the traits associated with this paintbrush.
2. Painting using this Revolver is the way of the Ravenclaw.
This is because it possesses one of the traits of a Ravenclaw; intelligence. It features an intelligent design that allows it to be used with any type of paintbrush (including the mini roller), it can be screwed onto an extension pole for painting high walls and the paintbrush can be rotated 360° to paint difficult angles.
3. Painting using a paintbrush that is heavily taped to an extension pole is the way of the Hufflepuff.
Hufflepuffs are known to be hardworking and dedicated to getting a job done. Instead of making life easier by using any of the tools above, they take the time to create one themselves. Not to mention that they will need to detach it and attach it again depending on the angle they need to paint.
4. Painting using a paintbrush and without an extension pole is the way of the Gryffindor.
Gryffindors are daring and brave. They will always find a way to get up there just so they can paint it by themselves.
