I wish I had the picture of the original quilt. It truly was something extra ordinary!
For each column two different fabrics are used. Total of 36 different fabrics were used and to avoid copying the original, this was made on a larger scale. With out a doubt, some of us long time quilters would have to do a lot of 'unlearning' if we wanted to replicate his quilt. We all know how hard that is!
Hope this answers any questions you might have.
