For my application last year I put that I was in the high school concert and marching bands, playing 1st chair trombone, A building and interior painter for 3 summers as my job, and an avid golfer and college basketball player. Basically anything that you do that uses your hands and eyes in conjunction with each other. The suggestions above are good examples also. I know a lot of female dental applicants I knew used to make jewelry and put that on their application as well... Good Luck!
