For this bulletin board I put up some practice reminders on the snowflakes.  I use this bulletin board after Christmas during the January blahs that seem to come every year.  It's quick, cute and easy.  I use some tips like:  

1.  Set goals for your practice time.

2.  Use a timer to help you get enough practice time in.

3.  Don't practice mistakes!  Practice small sections, measure by measure and then practice the whole piece correctly!

4.  Practice even if you don't want to.

5.  Remember that practice won't make perfect, but it will make better!
