00A.

First, make a rose.

This is an"Lovely Origami Rose".

OR

You can use "Pretty Origami Rose".

00B.

Make a calyx.

This is a Superior Origami Calyx that I am using here but you can use any other calyx.

Be aware of paper size depending upon rose you are using.

Since we are using "Lovely Origami Rose", we need to use a larger paper for the calyx.

00C.

Make a origami stem.

This is a Hollow Origami Stem.
