I was watching a speed paint one day when I saw the artist use a tool that allowed her to select an area around the boundaries of the lines.  Much of the time spent on pictures is used to carefully make sure I don't color out of the lines or blend over them.  Seeing this new technique (well new to me anyway) made me go looking for a new painting program.  The program she used was called SAI, so I looked that up first but you had to pay for it so I continued looking.  Eventually I discovered that PAINT.NET, one of the more popular free painting programs, let you draw a border for your selection area, which was the best thing I could find so I downloaded it.  While testing out the tools I discovered that the "magic wand" tool was exactly what I was looking for.  I seemed to recall that there was a magic wand tool on TwistedBrush Open Studio but it wasn't a magic wand selection tool, instead it was a masking tool, so I still needed PAINT.NET.  However, PAINT.NET doesn't have another important tool I use, the blender.  So from now on, I'll probably need to use both programs to quickly and effectively make pictures.  Maybe I'll buy a full program later, an ideal one would be one like twistedbrush but has a magic wand selection tool.  Until then I'm thankful for what I have, and before I buy a program I want it to be compatible with the Drawing tablet I plan to get.
