Gathering the hammock, and attaching the suspension
Once your hammock is sewn the next step is gathering the ends. There are numerous ways to do this, including methods which don't require the sewing of end channels in your fabric but I will leave those methods to people who have experience with them. These methods require the sewing of an end channel as detailed in part 1 of making a net-less camping hammock.
Essentially when gathering the ends of your hammock, you are simply inserting something through the channel and tightening it in order to essentially a ball of fabric.
The first method involves running your suspension directly through the channel e.g. your whoopie sling or continuous loop, and cinching tight. This produces a clean looking finish, and is the method probably most commonly used by camping hammock manufacturers. This method places stress on the end channel stitching so you want to ensure you lay down some solid stitches, and have at least 3 parallel rows using quality sewing thread. It is not recommended for lightweight fabrics, where failures have been known to occur. It also produces a consistent gather of the hammock without much fuss.
If attaching a whoopie sling insert the fixed loop through the end channel
Run the adjustable loop of the whoopie through the fixed loop
Cinch tight and you are done. (Note: in the photo below there is only 2 rows of stitches, 3 are recommended for this method)
This method involves running a cord, or some people use a cable (zip) tie, to gather the ends. Your suspension, e.g. whoopie sling or fixed loop, is then girth hitched over the hammock fabric below the gather you have just created. The gather prevents the suspension from slipping off the end of the hammock. This method does not place any stress on your end channel stitching, and is fine to use on lightweight fabrics as well as heavier fabrics. There is some minor fiddling required when attaching your suspension to ensure a consistent gather of the fabric. If you like being able to change out your suspension quickly or play with different setups this is the method for you.
Insert cord through end channel. In this instance I am using 2mm VB cord.
Next you can tie a knot as per Knotty's method on Hammock Forums, insert a cable (zip) tie, or use a small cord lock as I have done below.
The cord lock method leaves a length of cord, depending on how long you cut it, I use around 600-650mm, which you can attach a mitten hook to the end and this gives you an attachement point for a peak bag, pillow of whatever you want at the ends of the hammock.
Next you need to attach your suspension by girth hitching to the fabric below the gather. If using a whoopie sling you simply run the adjustable loop of the whoopie sling through the fixed loop of the whoopie, and cinch tight. You may need to move the fabric around a little to ensure the fabric is gathered consistently.
You can run the suspension over the top of the gather as per below,
or run your suspension through the middle of the gather as per the photo below
Rather than attach the whoopie sling directly to the hammock, another option is use a continuous loop which allows you to disconnect your whoopie sling from the hammock, or allows you to easily change between whoopie slings or webbing based suspensions. Another advantage is if the distance between your two anchor points is too close then the loops can be attached directly to your tree straps through the use of a marlin spike hitch.

There are many options when making hammocks, and those options listed above are but a few.
