Whipped up in the knick o' time for a teacher gift. Liked it so much I made a mess of notes so I could recreate it. Be kind it's my first written out pattern.

Both quick and easy peasy.

Here's what you'll need:
3 skeins of Paton's SWS
US K-ish crochet hook...mine is bamboo and not the standard, but as you're felting it anyway, gauge is not critical.
tapestry/yarn needle

lingerie bag

ivory liquid dish soap

washing machine with lots of hot water

doh! forgot to measure.

uh, does it matter if you're felting it anyway?

It took me a bit longer as I was figuring it out as I went along, but I
have to think you could whip this out in an evening, felt it before bed
and have it dry and ready to go the next day.
This
bag is worked in the round, starting with an oval to form the base of
the bag by working down one side of a chain and back on the other,
increasing each round to your desired size, then decreasing to bring
the sides up and angle them in. Once the decreases are done, you work
even rounds until shaping the handles. I started working spiral at that
point, but I would recommend not. Once it was felted, that part of the
bag seemed to twist a bit which made shaping more challenging than it
had to be. My guess is that by finishing off each round and chaining up
to start a new one that wouldn't happen. I used half double crochet
hoping for a nice, dense fabric after felting and that is just what
resulted.
