Solar projection is safe. Use a long focal length eyepiece, no need for high magnification on the sun. Something like a cheap 25 or 30mm Kellner or Plossl eyepiece will reveal sunspots and other features, and you can enjoy the projected image without having to reposition the scope every few seconds.
However, when projecting, you still have to be careful. Never, ever look directly down at your eyepiece. Use your telescope's shadow to find the sun, when the tube shadow looks like a circle/is at minimum, the sun will be shining out the eyepiece. Also you should keep the finder covered to avoid damaging it or worse yet burn your self or anything else.
When I project, I always stand well away from the eyepiece and make sure never to look directly into it or at it. I always keep my line of sight well away from the eyepiece.
Holding the projection screen/paper or whatever you are using at least 30cm from the eyepiece will yield good results. Too close and all you'll see is a blinding image with no features. You can use the telescopes focuser to get the image into focus as far from the eyepiece as you want until the image becomes too dim to see. Holding the projection screen 30-50cm from the eyepiece yields the best results IMO.
