I been doing hammocks for a number of years now. While I can hang my gathered end hammocks to where they are almost perfect there is always a bit of a calf ridge line. Not so bad I can't sleep in them but just enough to irritate me. In my basement where I like to test gear and lounge to read, the ridge line is pretty bad because of the two supports I use.
Was in conversation with JuneBugDawn. She told me "get one longer and wider" and your ridgeline will disappear. Since I really wanted something more comfortable for the basement area, I had her make me one. No, I don't sew and wanted channels in the ends rather than the stock W gather. WOW! is about all I can say.
The stock to make it comes from Table Cloth and it is 90x132". Mine happens to be brown but they offer many colors.
So, props to JuneBug and all I can say is size does matter!
