Repeat steps 16 and 17 on the other five triangle flaps.

Step 22:
Prefold the leaf paper in half, then fold over the two outer lines.

Step 28:
Fold the upper edge of the stem inwards, all around.

Step 25:
Curve the upper part of the leaf by rolling it up.

Step 26:
Make seven to ten of these leaves for one Amaryllis plant.

Step 23:
Fold over these two lines.

Step 29:
Glue the flowers to the top of the stem, in a circle.

Step 27:
Roll up a large green rectangle for the stem.

Step 30:
The leaves are glued to the lower part of the stem.
I made two of these Amaryllis flowering plants for my arrangement.

Step 31:
I used the same Origami paper for the Shooting Star flower and for the bud. One side is darker than the other. The bud is folded by using this darker colored side of the paper and the same way as the flower until step 40
Prefold over the four lines.

Step 32:
Fold over the prefolded lines, into a basic shape.

Step 33:
Fold the edge downwards

Step 35:
Flip the model upside down

Step 34:
Repeat step 33 on the other three edges.

Step 36:
Fold the center to the right

Step 37:
Fold the lower petal to the center over these two lines.

Step 38:
This is how the backside / bottom looks.
Flip the model again.

Step 39:
Open each petal and squash-fold it towards the center.

Step 40:
Curve the tip of each petal by rolling it up tightly.

Step 41:
I'm not sure how many of these flowers I made, I think about 50 to 60 for this arrangement.

Step 42:
The Shooting Star Bud is folded the same as the flower, until step 40.
Curve and glue the petal tips together, see arrows.

Step 43:
Make 10 to 15 of these flower buds

Step 44:
Prefold the Shooting Star leaf in half, then fold over the two outer lines.

Step 45:
Fold over these two lines.

Step 46:
Fold the lower part of the leaf in half and curve the upper part outwards.

Step 47:
The leaves are used for the flowers and buds of the Shooting Stars.

Step 48:
Fold a long rectangle around a metal / florist wire.
Curve the stem a little to make it look more natural and realistic.

Step 49:
The flowers and buds are glued to the upper part of each stem. The leaves are folded around the lower part of the stems.
I clustered the flowers and buds into large clumps, see the next photos.
