Thanks so very much for all your suggestions. I think the easiest for me will be laughinquilter's idea of 10" strips of jungle and a row 4 square blocks in between those. I've always liked that design in other's quilts.
Amazon's quick blocks tutorial idea is another that would be good for this, but I'm too scared to try it now since I'm in a big hurry to finish this.
As always, craftybear offered several suggestions, and I do appreciate all the help given to me.
Thanks everybody!
