Aaaargh....Ripping, ripping and more ripping!

I seem to have lost my knitting and crochet mojo. The last couple of weeks or so have been really frustrating. Everytime I try to tackle a project of some kind, I keep finding myself unhappy with the look or the feel of it and so I keeping ripping them all back to start again. Has this ever happened to you?
But looking on the bright side at least it gives my fingers something to do and keeps me out of mischief.
