Whole feedsack, 1940s or 50s vintage cotton fabric with snowflakes print - I've never seen this print before, seasonal prints are uncommon, hard to find!
This is still sewn up as a bag with the original chain stitching, measures 21" (42" fabric) x 36". The open end has had metal grommets added to make this a laundry bag or something similar, though it doesn't look as if it was ever used for the purpose. It's clean and nice without fading, holes or spots.
