I made one of those bags a few years ago. Can't find the pattern but will keep looking I'm sure it was British pat whorl and quilting or poplar patchwork British copy. I made the bag for a friend for gardening sorry she has moved and lives based in a touring caravan no idea where she is.
I can remember thinking when I made the bag looke at
http://pursepatternnews.blogspot.com...1_archive.html for idea of shape or this pattern.
.i would make one of those bag liners which can be inserted to bag and is loose if I made another one. It does need a firm base for bottles .
