Switching into drawing mode can be challenging, especially if you are just starting out. Here are some useful tips to help you get in the drawing state of mind:
Loosen Up! Shake out your hands and loosen your grip on your pencil and just sketch loosely.
Try different supplies! Don’t feel restricted to a pencil. If you are used to ‘writing’ with a pencil and pen, try picking up a marker or crayon...something different than you usually “write” with.
