OK, I used to have this problem with particular pieces of fabric that I just fell in love with and couldn't bring myself to cut it..
As a result, I still had some fabric from when I was a teen.
Then, I lost it all, along with all my other possessions, in a house fire.
Moral of the story: go ahead and CUT IT UP....you will be happy once you have used it, you will have put it to good use, and you can go shopping for some more.
I have no problem cutting up fabric now...
