I'm learning a new computer skill! We are thinking of doing some "patio" work this spring and need to be able to visualize what things will look like before diving in.  I had seen Google "Sketchup" before.  It's a free program sortof like Autocad.   I've spent days on tutorials and now I'm starting to draw our house using the old blueprints so I'll have the dimensions correct.  This is just a start - lots of details to add (and a roof!!)  Fun though!
