I sewed up the sides of my sprang water bottle carrier, put in a temporary string strap, and tried it out.
The seams look haphazard.
The fabric is thin and long when at rest.
This is the first time I've made any sort of cloth with handspun Wensleydale wool and I love how hairy the texture is.
That which was to be proved: sprang fabric shortens as it stretches outward.
One of those curvy bottles of French pink lemonade would look great in this thing.
