What are you chasing ?
Soft (fur on) leather or bunny rawhide ?
Quick and easy:
Stretch the skin(s) and tack them taught.
Scrape the flesh side clean and cover with salt.
Leave for a day or two in a cool, dark place (garage is ideal).
Scrape off excess salt, rinse in clean water if you like (not necessary), and repeat another once or twice.
You can 'tan' rabbit using tallow or natural hand creams because it's so thin. Cat skins can be done the same way (don't ask me how I know this
) but be careful - you can easily tear dry rabbit skins when rubbing the hand cream in and softening it.
I often rinse the skins well in rain water and allow them to dry naturally after the last salting.
Thee's a great method listed on this site:

Rabbit skins were cut into strips about an inch wide and made into rawhide and loosely woven into blankets by Native Americans.
