Take a look at this Pattern Service booklet "for sewing with Cotton Bags", put out by Simplicity and the National Cotton Council in 1952. Often called Feed Sacks, these were sold holding products in the hope that the wife would insist on hubby buying the same brand so she could get enough of any one print to actually make something.
"Though your husband has been buying farm commodities in cotton bags and you have been sewing with them for years, it's possible that neither of you has realized what a bargain you are getting....And cotton bag fabrics this year are more beautiful than ever. There are smart plaids, florals, stripes, checks, modern designs, polka dots and conversational prints adaptable to a host of sewing needs...Dress print fertilizer bags have joined the fashion parade. And do you realize that with a ton of fertilizer, cotton containers bring you more than 20 yards of re-usable fabric?"
These patterns each list how many sacks you'd need to make the outfit. More tomorrow!
