Concept: Off-the-charts campy.
Utility: Surprisingly useful, since a glass kettle leaks heat like crazy.
Execution: Pretty sleek!

Used up a most of a ball of Kureyon and a few yards of some anonymous black wool.

Since I couldn’t pack the kettle with me to measure it, I measured the kettle with a piece of string. I wrapped the string around the top of the kettle and made a knot where the string met itself, then measured again an inch lower, made another knot at the circumference at that point, and so on an inch at a time down to the bottom of the kettle. The string ended up looking like this, with x’s for knots:

X-----------------------x--------X----X---X---X

… so I cast on for the distance from the first knot to the second, plus extra for a garter-stitch button band. Over the next inch of fabric, I increased evenly until the piece was as wide as the distance from the first knot to the third, and so on. Super useful!
