I have made a similar quilt (the rainbow one a few days back). I cut the batiks this time and the white was left intact as the strips were placed. I used 2 1/2" strips of batiks WOF and 2 1/2" strips of white, half of WOF. They were sewn into tubes- that is the batik to the white on both short ends. Then I laid them on the floor (getting too old for the floor), and arranged the colors. Satisfied with the color strip arrangement, I cut the colors to stagger the whites and have different lengths of batiks at the top and bottom. When all were cut, I used blue painters tape and numbered each strip from left to right. I put the number 2 strip face down on the number one and pinned the right edge. Every pair was pinned the same way. Now all the strips are in an envelope and I will see if my mom will sew the long edges. She is having some eye surgery next week, so I may have to wait. I have plenty of other quilts to sew. I took the photos at night and the colors are a bit tough to see, but I needed to get those strips off the floor before Tugger the terrible cat rearranged them.
