With the"create line" tool connect the vertex in the three shapes, working always from the eye and moving outwards (this is important).
Remove both shapes cloned previously and the useless segments in the first shape.
Now select the central vertexes of each line, Right-click and soften the shapes by selecting the "Smooth" option from the pop-up menu.
The last stage of modelling should be to move the vertexes at the ends to add a bit of randomness to the lashes. Also we can group some of the ends of the lashes to simulate clumping. This is best applied to the longer lashes, and bear in mind that we will be adding an opacity map later which will clip the ends of the lashes.
Now simply assign a very dark brown standard material to the lashes and put a gradient map in the "opacity" slot.
Finally, repeat the whole process for the upper lashes and make a mirror of both shapes to locate them in the other eye. Again, you may wish to tweak the end vertexes to add randomness to the lashes. There, it's easy See? :)
