The second clue would be the small knitting project in progress. If that project is almost done you will also find the next project or skein of yarn for the latest 1 skein wonder.
Then there is the small zippered pouch that has at least the following items in it. A small pair of scissors, a few extra stitch markers, darning needles, at least 1 crochet hook and a tape measure. Depending on the current work in progress you might also find cable holders, small bobbins for bits of yarn, dental floss for lace knitting and stitch holders.
Then we can't forget about the nail file so we don't snag our work. Lotion and nail creams to keep our hands soft so we don't snag things like silk.
I often wonder if our male counter parts keep their knitting in small backpacks. Do you have a knitters purse?
