Welcome! Here's a few pieces of advice:
RESEARCH. Take the time to read what others have done and reported here. Find out what has worked for others. Once you have an idea of the basics, it's all a matter of personal preference.
PRACTICE. Practice setting up and using your hammock in your back yard or somewhere you can walk to your house from. It won't take long to get the hang of things (hehe), but it's better to learn from your mistakes where you can recover in safety. The trail or deep woods is not the place to learn you didn't bring enough insulation.
RELAX. It's what this is all about after all is said and done. Enjoy yourself!
