This is a vintage Indygo Junction "Too Many Scraps" vest sewing pattern.
The pattern was designed by Sandy Belt and can be used for two quilted vests in sizes S-XL. There is a paper that lists the needed materials, a paper with the patchwork layout, and the pattern itself is printed on a large piece of thin paper.
The three papers each measure approximately 5.5" wide and 8.5" long, while the pattern, when folded, measures approximately 4.75" wide, 7.25" long, and 0.25" tall.
This set comes in very good pre-owned condition.
