I have to say, I would never have pegged some of my fabrics as 30s, however, let me be quick to add, they all came from charm packs very clearly marked "30s Charm Pack".
There were plaids, dots, and some [sort of] geometrics along with the expected florals. Other of the charms were so typically 30s I never had a doubt. Smiles and hugs to all!
I have a quilt made of 30s, 40s and a very few 50s fabrics, all from feed sacks. My grandmother started it and my mother finished it. As a young girl, I remember waiting for the feed delivery so my sisters and I could pick out the bags we wanted them to leave to get the least ugly fabrics. If none of us were there, the delivery guys would leave the ugliest ones that no one else would want. LOL We had to be picky, we were going to be wearing those sacks to school!!
