I made this one for my grandson. I don't know how to post a picture for you, but can tell you I used a red quilted fabric for the bag itself, bought the braided sew in handles for durability and then stitched two rows of crayon fabric all round the bag with slot that held a box of 24 crayons. He loved it.
