Quick answer-you cut three photos into narrow but equal strips, sew them together alternating the strips (1,2,3,1,2,3,1,2,3 etc). After they are all sewn into one long strip, begin to make seams by leaving all the number ones and sewing the number twos to the back of the number three strips, creating pleats, repeat across the sewn strip. Not sure how to sew the top and bottom of the strip so that all three pictures are visible though, I guess you will have to by her pattern..... ��
