A few weeks ago, I found myself on crutches due to a sprained ankle.  The lack of mobility drove me insane, as I am usually on the go at all times, but I think that I made good use of some of the down time.  I made a set of decorative arm rest and hand grip cushions for my crutches. 

The accessories for my crutches made them a little more bearable, but luckily, I'm back on my feet now.  :)
