Clueless Quilter

I was wondering if there is anyone with knowledge of dating fabric?
I am attaching (hopefully) a picture of two pieces of fabric and I am hoping that someone can give me an idea of the decade they may be from.

I have made a small quilt top from diamonds cut out by my great-grandmother in the late 40's to early 50's. The fabrics she used were scraps from her and my grandmothers 'house' dresses and aprons. I need 8 diamonds to add to some leftover diamonds, that I didn't use in the center, to make a border. These 2 fabric come from a box of scrapes that came from my grandmothers but could easily be from later decades, I just don't know.

Thanks for any help you can give.
