A six-pointed star from six 1:√3 rectangles. The unit only needs three folds and one more for the lock.

The other side shows the pinwheel nature of the star

A nine-pointed star from A8 1:√2 rectangles. I thought there should be 10 units but nine fit better.

The other side shows has a clearer structure and cleaner appearence?

Eight-pointed star folded from eight 3:2 rectangles.

A similar folding method as before, but I had to model the unit in Geogebra to find that the required proportion was 3:2.

As with the previous stars, the reverse side has a clean and clear structure

Having made 6- and 8-pointed stars, the next step was to make 3- to 7-pointed stars.

I eventually found the required proportions after more experimenting in Geogebra. For a short edge of 1 unit, the long edge needs to be 3.73, 2.41, 2.0, 1.73 and 1.6 for 3- to 7-points.

Odd numbers of units are awkward for choosing colours: either every unit a different colour or use 2 or 3 colours.

As the number of units goes up and beyond 10, the folded locking flap becomes tiny and almost useless.
