This was a gift for a friend. She had asked about a crocheted water bottle carrier. So, I searched online. I found a few options.
I ended up using this pattern from Vallieskids Blog. I think I made only slight changes on the handle and maybe the top band.
Here is the result:
My friend wanted the handle to be long enough to go across the body. I, of course, had to add a flower. I think this can stretch to fit a variety of different sized water bottles.
