Here's how we do it:
1/4" dowels 24" long with plastic nocks and leather blunts.

Cut a piece of leather in this shape and coat one side with rubber cement Tear Mender works great!):

Roll up the narrow part so it's the same diameter as the shaft:

Lay the shaft on the flap butted up to the roll:

Keep rolling until you like the size:

Smooth and trim as you see fit and voila!:

You can put points on them too, but these little blunts work well, hit hard but are still pretty safe.
