This quilt top came together with much appreciated help from PaperPrincess who helped me with the calculations when my brain just gave up and was about to explode
Thank you PaperPrincess! GingerK, I collected the fabric over a period of about two months. It wasn't as daunting as I initially thought it would be. I decided what size I wanted the picture blocks to be, then carried around a template which I placed over various fabrics every time I was fabric shopping. This helped enormously in selecting the right fabrics. It was a really fun quilt to make and I will definitely be making more.
