Today's pic: Coughlan's Double Wide Backwoods Mosquito Net???
I'm working on a (Covid) project that started with two of these. Mine measures 59" tall, so I felt the need to add height ... the reason for two. The plan is to splice about 2 feet of one to the bottom of the other making my height 7 feet tall (as opposed to just short of 5 feet with a single netting set. The 2 foot splice uses the "top" two feet (inverted) so I can have anchor points on the bottom (as well as hanging points on the top). So, think in terms of a netting cube. However, I've cut the bottom open, leaving about 1 foot of netting that will allow me to add some weight to ultimately hold the bottom down in windy conditions (in addition to the anchor points at the bottom). I'll ultimately double this netting over and had some relatively lightweight fabric to this interior edge that is more abrasive resistant.
Conceptually, this sounds pretty simple. However, as you know, there is a problem in that the netting is stretchy. I've countered this by adding grosgrain ribbon along the top and bottom edges and each side of the splice line. In doing so, I've added grosgrain loops (rather than metal rings) as line-out and anchor points (a total of 6 around each perimeter). Of course, the grosgrain ribbon has very limited stretch so the final product should be very much cube-like.
I'll decide if I need to also add vertical edges at the corners after the top/bottom pieces have been spliced together. The plan also calls for adding a 6 foot zipper on one of the longer sides. This should allow 2 people to enter/leave the enclosure without crawling over each other. I think 3 people inside would be REAL cozy.
At this size, I'm not sure if I'll need a center "lift" loop on the top.
If you decide you want to embark on a project like this, you might take the following into consideration. Sewing mosquito netting is a tad challenging. Let's just say that at times it has begun to feel very much like trying to construct a tutu for an elephant. At least it is keeping me "entertained" since I'm spending quite a lot more time at home than would be typical for me.

I'm hoping to bring in the final design in under 1.5 pounds total weight (netting only; not including lines, stakes or poles).
