Hi Becky and welcome from Australia. You are doing a wonderful thing.
My parents came from Poland and migrated to Australia in 1949. Like Trisha I remember my mother sending parcels to her sisters in Poland and they were wrapped in fabric and stitched up to keep them together. I'm know some of the goods 'disappeared' before the parcels reached their destination but at least they got something.
Becky please PM me as I would love to send you some fabric as I have a large stash.
Happy quilting.
