Yes, it is a ton of work. That's why so many people do the pointed ends. You just do your blades a little longer, fold the fan in half with right dudes together and sew a 1/4 inch seam across the end. You just pop the pointed end out and it us ready to go.
If you love the look of rounded ends, you can find other options. There is the innerfacing trick or raw edge applique as well. If you decide to iron the edges instead, don't look at how many you need to do just concentrate on one block at a time. You can do it!
