Sorry, should have mentioned - Although all are scrappy, in 1st (Carolina Christmas) and 3rd (Easy Street), I used strips cut per Bonnie's Scrap User's System as well as fat quarters. Variety is the spice of life, and of my quilts! Recently, I had to make a project using only 4 fabrics and not only found it difficult, I didn't care for the end result!
So while you have large scraps left, and I wouldn't cut them all the way down to strings, I'd start cutting them into strips and squares...
Also love Joan Ford (Hummingbird Highway) patterns; she has two books on Scrap Therapy out, both of which are well worth it.
