Narration : 6. Pleated Filter Paper 1

First, fold the filter paper in half.
Next, repeat by folding in half.
By doing so, two compartments are formed.
First, press and open out one compartment.
While aligning the center of the fold with the crease below press out the other compartment and both sides will be creased.
Do the similar with the other compartment too.
While folding, be careful not to fold right to the center as this will weaken the filter paper.
In the end refold the central mountain fold to a valley fold.
This is the basic pattern for folding.
This will leave you with four folds.
In the case of all four folds repeat the basic folding pattern.
Then you will have eight folds.
If the filter paper is small this folding is enough.
When you repeat the same with the eight folds you will have the usual 16 fold paper.
Spread it open to fit the funnel.
