Inset or Y-seams galore! In looking over some of the blocks, it appears as if I cut some of the white background pieces too short, as I had to add bits more. This block doesn't show it thankfully.
The patterned fabric is all old feedsack or cotton sewing fabric, obtained on ebay or various sources. Solids are new fabrics. This quilt is now assembled and I started quilting it, till I stalled (as is typical for me).
