Tip of the day: Get it in the right spot.

Ever start drawing and you're really into it, getting all the details just right to nearly finish the piece and find that it is in the wrong spot on your page or canvas... whatever? Done it a zillion times.
Tip: Sketch a box on your paper/canvas where you want your figure to be. Make the box the size and dimensions you expect. Then sketch your big shapes first making corrections when needed. Save the details for last.
Whether you're copying from a reference, drawing real life subject/s, or working in abstract, organizing your canvas/paper this way helps a lot.
