For this jar I used about 120 gram t-shirt yarn which you can buy here, a jar, a 10mm crochet needle and a piece of 10mm satin ribbon 30 inch long.
Crochet a chain in slipstitch that fits your jar and close it with a half crochet, for my jar I made 20 slipstitches
Than work in single crochet and work till your work is as high as your jar and finish your work.
Put it around your jar and work your satin ribbon through and make a little bow
You can use your jar for your pencils or other things,
or you can put candle in it!
