American goats

Take two matches and put them between thumb and forefinger of left hand. Follow the picture A, so intertwist other four matches, so some kind of rack will be made D.

On picture C you can see some kind of stronger goat. You can take three matches instead of two and insert other two matches.

And afterthat, intertwist other matches, defined by numbers 1,2,3,4 as picture A shows.

Goat D and C can be extended in the way that one side can be elevated carefully by one match and than insert two matches in the way how goat D and B is made.

You can make this structure (as picture D shows) in many different proportions.
