The Turkish Stitch used for the body of the bag is one of the family of faggotting stitches that goes back to knitting antiquity. Its purled cousin is called Purse Stitch, which indicates its historic use for objects like this string bag.
This bag can be knitted in any string or thread--preferably of a non-stretching fiber like cotton--from crochet cotton to sport weight, maybe thicker, using any very large needle size. This pattern is about as "mindless" as knitting gets, and goes very fast.
16" circular needle, size US 13 (9 mm). Double points will work, but are a lot fussier.
Continuing from the corner where the final row finishes, pick up and knit 15 stitches along each of the other three sides of the square (total 60 stitches). Place a marker; this will be the beginning of the round for the body of the bag.
Double the stitch count by working (YO, K1) around (120 sts).
Work back and forth in garter stitch (knit every row) until strap measures 12 to 18 inches long when stretched smooth. The one in the photo was 24 inches and stretched way too long!
Slide the 15 stitches from the holder onto a spare needle of any size. Carefully align the two needles so that they are both pointing the same direction and the right sides of the fabric are together; your goal is to do a 3-needle bindoff to join the strap to the far side of the bag without twisting it, and with the seam on the inside.
Do the same for the next stitch on each needle. Pass the first stitch over the second stitch. One stitch bound off.
Continue until all stitches are bound off and the strap is joined. Make sure it's right before cutting the thread and tying off the end.
Enterprising knitter Karen Fegelman used thick yarn and a cast-on of only 5 stitches to make a Bag Hat for her daughter.
Late-breaking news: a local knitter accidentally made a contrast band around the center of her bag but didn't know how she had done it. It looked very nice, and it would be worth discovering how it was done. I suspect she just zoned out and continued for several rounds forgetting to switch back and forth between Round 1 and Round 2. I haven't tried it yet, but if you do, please report back!
