Reconstruct a diagram where 10 straight lines, of finite length, form 12 intersections, viz:

----------------------
Intersections      by
   formed        Lines
    7              2
    4              3
    1              4
----------------------

Describe this relatively simple arrangement.

(In reply to Looked at solution, still confused (no spoiler) by Larry)

I've added an ascii sketch to the solution.
Draw it yourself and then count.
