i have just finished my gathered end hammock. i have hung in it for about a total of 7 hours over the last week or so. My son and i just hung it in his room so he can see if he wants to give up his bed and when i tried it out the whipping came off the end. i really thought it was tight but i guess it could have come loose. Is there anything i should have done to the ends to keep this from happening?????
