Christmas Fun.

Fun that's free: Who doesn't want that? Save any decorative paper that you have left over from presents, especially the holographic, sparkly, twinkly and shiny types. Small pieces are fine for the stars themselves or to decorate plainer paper. ( Get family and friends to give you theirs.)  Fun, Fun, Fun. Have a great craft day and share this instructable with others. Fun that's free.

[[ Please note]] I have added some extra explanations where It was called for. I am unable to remake the Instructable (no camera) so feel free to ask any questions and I promise to reply. Craftv.

 I square piece of paper (that's it).

Size: For the purposes of the Instructable I have used a two sided paper so you can see more easily which is front and back. 
The patterned side will be the star.
You can use plain white paper, If you mess up as you practice that's all it costs, 1 piece of paper.
The size of the square will be the same size as the completed star.
The larger silver and red stars are made of 3 layers of Holographic paper, one on top of the other. [They look like 3D.]
 
For the purposes of this instruction I shall say patterned or plain side of paper (even though you may not be using a one sided paper).

Lay paper down with plain side facing you.

Fold plain side edge to edge and crease well. Open up and repeat for other two edges, crease well. Open up and see the crossed lines through the middle.  

Fold the patterned side together point to point across the diagonal and crease well. Fold across the other diagonal and crease well. Open up and see the crossed lines in place.
[NOTE] Apologies . Please flip the paper to the patterned side before this fold. The result is valley folds edge to edge and mountain folds across the diagonal.

Push the diagonal lines inward (plain on the inside)  this will collapse the large square into a small square (see picture).

[NOTE] the centre of the star is away from you at the top of the picture.
Take the left point and fold to meet the centre line.    Crease well (leave in place).
Take the right point and fold to meet the centre line. Crease well. (leave in place). 


Flip completely over and repeat. All four points should now be in place and look like a kite.

This is the completed kite shape.

At the top of the kite shape is a small triangle. Fold it  forward across to make a crease that marks the line for future reference. This not used at this time.

NOTE: The kite is flattened out to show the un-split kite shape towards you . Take the un-split long bottom point and lift up.

NOTE: The star is in the same place and direction.
I have moved to the top so you can see better. Do not alter your seated position.

When you pull up the long point the edge will start to fold in automatically,help it along and crease well into place.

Fold all edges down and reach this diamond shape. Crease well.

The long points of the diamond will split apart (like legs) They are NOT CUT (just looks that way).

When all four points are folded up they will look like a four point tree.

This is just another, neater, view of the previous step.

As shown fold up the two bottom corners to meet at the centre line. Crease well.

Flip over and fold the remaining short points to meet at  the the centre line. Crease well.

Place four fingers under the piece and hold the four short points you just folded in steps 16 +17.
 Place two thumbs inside and hold together, as shown

This is another view of my fingers in place as in the previous step. Hold in-place and Gently pull apart and the centre square of the star will begin to appear.

Continue gently pulling until the centre square is fully revealed. You may need to tease it a little so that it stays straight and square.

Flatten the star and neaten if required. Well done , that's it.
Look how good they are sparkling and twinkling in the sun. Join two or three stars on top of each other, either same size or slightly smaller and they gain added dimension.
