The first step to starting an arts and crafts session is to collect everything that you're going to need to make some pretty creations.

A little known secret of professional artists is that they are all able to keep their hands extremely calm while working with their art mediums. If your hand tends to tremble uncontrollably then you might find drawing straight lines to be very difficult if not almost impossible.
