I do the same...I've seen alot of guys "first attempts" butcher a beautiful piece of wood by not honing their skills on scrap lumber.
In old days, a craftsman would develop the ability to do beautiful work and also complete his tasks with economy of motion(s). One such example of expertise that comes to mind would be the carving of a carousel horse. At the turn of the LAST century, a skilled craftsmen could carve an elaborate horse in a normal workweek (albeit not 40 hours). Just imagine the time it would take a "hobbyist" to do the same today.
Almost all of us hobbyists can make some amazing stuff just be taking time, careful study, and thinking about what steps you need to take before you take them, thus avoiding mistakes (my long-past neighbor, an old navy carpenter's mate, often quipped "I've cut this board 3 times and it's still too short." HA HA :haha:
Keep up the careful work...it will show in your finished product! :v
