While your piece is wet, you will want to take some time to stretch and manipulate it into shape. You can try holding it in place by covering it with a second clean, dry towel and then setting heavy objects on top of it. Make sure you check your piece often though to make sure it is drying okay. You certainly do not want it to start to rot after all your hard work!
Make sure your item does get as much air circulating around it as possible, turning it over occasionally might help speed the process. Don't be surprised, however, if your project takes a couple days to dry.
Once it is dry you can add some finishing touches...
