Those look like genuine feed sack prints to me!
Bubblegum pink quarter circles...
...and hand stitched seams. These are no where near that standard 1/4" we expect to see today.
I had a thrifted pink cotton shirt in my stash that is soooooo close to that same bubble gum pink. It was a small shirt, so I had to piece some of the background blocks together. I fused the blocks to the background, simply because I don't expect those teeny seams, and old thread to hold together. Then I used a tiny blanket stitch around the edges of the fan blades.
Thirteen blocks. These blocks are 6.5" (unfinished). I have no idea what I'm going to do with these...a miniature quilt? A doll quilt? A pillow? I intend to trim the blocks down a bit to remove some of the solid colour and let the prints sing out a little louder.
