Crescent Moon & Star
A quick make for Ramadan. The star instructions are here folded from a 14cm square and I used the Moon instructions from here , and used a piece of card but converted to cm using 9cm radius, 6.75cm radius and 7.5 cm radius. There's a nice opportunity for construction/loci to find the centre of the crease circle when doing the moon. In creating a star, you first fold to make and cut a pentagon.
