In this tutorial #138 there was a step that was really challenging to me. I had to use the pen tool and draw a four pointed star which took me a while to do. The rest of the steps were pretty easy for me and I did not have any problems with. One of the techniques I learned in this tutorial which is how to make a four pointed start while using the pen tool. Another technique I learned was how to move the shape that I drew form being horizontal to diagonal.
