Pins and Needles.  First thought was pine needles, but the class has had a large number of those.  Then pin cushions, again a bunch.  So I guess I'm sitting on pins and needles as to when the balloon will pop.  

 Crystalized the icicles in photoshop.  Couldn't figure out how to get rid of the tiny lines that defined what crystalized and what didn't.  With temps at zero all week, these little icicles were the result of the only couple of hours of sun on the barn roof. 

 Obsessive/compulsive was the challenge.  A hard one for me since you can see I'm not that.  I didn't notice the diagonal lines on the mat were off center until I was uploading the photo.
