Finger hinges

Finger hinges are my favorite piece ever - mainly due to this technique. They're a great way to get a relatively compact and sturdy 180 degree stud reversal. Another part that you can use in similar way is the old school roof hinge.

To find the different pieces needed for this technique you can search LEGO's online Pick-a-Brick for the design ID's. We link other market places directly on each individual piece page, which you can find below.
