So I found this tutorial that seemed really nice how to make things look like they grow. > **[Mask Animation in Flash Tutorial: An Angel Grows Wings](http://gomedia.com/zine/tutorials/an-angel-grows-wings-animated-mask-in-flash/)** > > Mask Animation in Flash Tutorial: An Angel Grows Wings - Source files included. Follow along and nail your technique! The only thing is though I cant get it to work properly 😕 I follow the tutorial step by step but end up with very weird results… Im first creating the mask just like they do with the pen tool. Then turn the lines into fills and then shape tween them all. The problem is I get skewing and when I drag the timeline it looks like the lines is flipping around at some frames. It doesnt follow the line I dragged out from start. Else from that I cant get the actually movieclip to play either from the way they do it. I really really need this to work so pls help 🙂 Provided my testfile to actually see what is happening. [My test fla](http://bart.sm.luth.se/%7Ecamsch-4/stuff/test_mask.fla)
