French Angoras have clean feet, ears and faces. Which means the hair stays short in those areas. You are probably thinking of an english angora - they have wool EVERY WHERE!!!!
I harvest my frenchies twice a year, mainly because they show rabbits and the longer the wool the better. The raw fiber sells by the pound and it varies greatly depending on where you are, what color it is, etc. You can easily spin it with a lace weight drop spindle or an electric one. The price on the spun wool also varies but is typically much higher than the raw wool.
Also, I would never let them run in the grass unless your grass is FREE of all else. No stickers, no other debris their wool can pick up. Because it is a PAIN to get it all out of their wool.
Right now, there is a low demand for all rabbits except meat ones. However, once things pick up, they do sell well, especially if they are pedigreed. Mine are selling, just slowly. I had 8 kits and we have 3 left, they are now 12 weeks.
