I had trouble here too, Shirley. Do you see the big spool that is next to the crates? Jump on that first, and from there you should be able to make the ledge. And don't forget you can do a running jump, which will take you higher and farther. I actually had more trouble jumping over to the other ledge--I must have tried that a dozen times or more before I finally made it.
One last thing, you must jump onto the crates to the
right of the door, and then jump the gap in the ledge to reach the journey cloth...
