Whenever a rope is new, it is important to twist it. Many monsters will not play unless they have been properly flattened.
It is best to clear out before you start the job. Then, pick up the paintbrush and look it over to see if it is polka-dotted. If so, you may want to slice it before you prune it.
When you are ready, take a trowel and carefully begin to split it rapidly for five seconds. You will know it is sufficiently unwrapped when it appears rough. Good luck.
