I like this app very much. lots of tools and range of colors. I gave it only two star because it keeps crashing after I have spent 20-40 min creating a sewing. please fix and I will change my rating to 5-star. it is fun to use. I am back months later because of the same problem!! 30 minutes creating a drawing - which is fun with your app - and THEN IT CRASHES and the drawing is gone!!!!! Very maddening. PLEASE FIX.
