Sand and cove went great and looks fine. Liner is beaded new liner was called a uni-bead and should have fit. After a few attempts figured out how to get bead to drop in track fairly easily but when we reached the starting point we still had about 10 inches of extra material. Unhooked everything and second time we triedhooking bead in a star pattern going back and forth accross pool. When we got to the last few sections we still had the same problem only now instead of one larg e piece of extra material we have several sections with just an inch or two extra. not sure what to do. Iam going to post this under a new heading as well. Trying to get set for daughters bday party in 1 week , help.
