Getting rid of scraps

I started making some string blocks. I have been organizing my stash and I have found lots of fabrics I didn't even remember buying. I also have bags and bags of scraps that I couldn't throw away -- so the other day I started making string blocks. I am not really being picky about what fabrics go next to each other -- its scrappy after all. I have made 12 blocks and think I will need another 68 to make a quilt that will measure 64 x 80 without borders.  Wonder how long this project will take me?   I will post some pictures of the blocks as soon as possible.
