Please don’t knit a felted bag when you have travelled for ten hours in fog and the freezing cold, and have only had 5 hours sleep. You will misalign the corners of the base and the handles so that the bag is mis-shapen and not fit to be given as a christmas present.
However it will probably be ok just to store a knitting project by your bed or something.
Please don’t regret too much that you’ve just felted 3 skeins of yarn that you actually liked, and can’t get back.
bet felted flowers look good to you right about now.
