Digital Counter

I feel its impossible to make the counter from a D flip flop or JK flip flop. These FF increase or decrease by the count of 1. You cannot get the sequence which you need.

My personal method would be to use a microcontroller. One chip would do it all and more.

What do you want to use simple LEDs or a LED display?
Dont mind but i want to ask why do you only want to make it from scratch? ???
Where do you want to apply it?
