I recently was given several flour sacks by a friend's mom who had them in storage for a long time. There are probably around 12-15 of them. Some have some staining from storage. Can I get that out?

Also, they are all white. Is there any reproduction type fabric that would go well with the flour sack fabric to make a quilt? Or any other projects that I could be making with them?

Thanks ahead for helping me brain storm!
