Finalist in the
Sew Warm Contest
Well, I like to hike. I like to spend night in the Outdoors, on mountain summits. Therefore I need a shelter. A light one. Small one. Cheap one. No fiber poles. And there is an enormous choice on *-bays today. Still, the price and what I like rarely match.
So, DIY necessity was a way to get what I want... and here is a result.
Step 1: Testing of Idea
Well. I took my hiker stick, thin ropes and assembled how the tent should look like in nature and to get proper feeling how it shall be as well. Of course, rope-line shall help to determine dimensions. I put my self in....... and this evening decision about everything was made.
Step 2: Idea
First, some limitations. I like to have light tent. I do not like fiber.poles. They are extra weight and they brake, especially when you are far away. I use, at my hiking's trips, my "third" leg to help me. This is is a long bamboo stick as you can see on pictures. It shall serve overnight as center pole in my tent. So, only fabric material suitable for this purpose.
I found a car shelter, action in shop, very cheap and decide to use this for outer layer on my tent. In the nearby shop I found inner material, usually used for umbrella, and it suit to me as well. So material was decided. Old domestic curtain shall be used for air vents and mosquitio net.
So I start with paperwork ... as you can see.
Step 3: KPteepee Wigwam on Paper
Voila! This is what I want. The measurements are just fine for me and my bamboo stick. Practically, this tent is comfortable for two person!
I am alone, so I shall have plenty of space for my all gear. This is two layer tent, outer waterproof and breathable inner layer to preserve warm and reduce moisture condensation.
Step 4: Sewing
After I study a way of sewing, I decide to use so called "French saw", to get strengths and reduce rain drops getting through. Anyway, later shall be silicon applied on each sew.
Step 5: Triangles Calculation
OK, my tent shall be made from 8-angle bottom and 8 identical triangles (inner smaller) and 8 (outer-bigger), where one shall be made from mosquito net and as door in inner layer. I also provided air vents on tent summit, 4 on inside layer and 2 on outer layer. Here is the drawing/measurement of each triangle.
Step 6: Matrix
To get identical triangles, I took a 4 mm thick 50 mm wide pressed fiberboard strips, and formed a triangle with inner side exact measurements of my planned triangles. Most important was horizontal strip with exact width of triangle.
All strips are connected with screws with fly-nut and serve for both types of triangles.
Step 7: Marking Sew Line
On each exact line of triangle I add 5 mm + 10 mm for overlap to get "French" sew. This was also used where-ever is needed to extend/add fabric as well.
Step 8: Adding a Net As Airwent
Here are pictures of how I extend inner fabric with the same fabric to get right surface and mosquito net for air went on tent top. I took two pieces, mark a line of 10 mm on each. Then I use moment glue and apply on both very softly, mostly as a line of small drops. After few minutes drying, I pressed them together. This help is needed for easier handling by sewing. I overlap net 10 mm, press with hot iron, then bend back net to get 10 mm strip, pressed with hot iron again. and sew on machine with thin needle number 60 - (70 is also OK), first from one side near line of overlap and then from other side to get double stitch.
Step 9: Making Flat Ropes for Pegs
It remain a plenty of material/fabric as surplus so I decide to sew flat ropes on each (2 x 8pcs) corner/angle on inner and outer layer, for tighten them on pegs. I draw 35 mm wide strips and cut them accordingly. The I sew each long side to together. Then I use a thin wire double length of my strips, bend it on half and push the through strip. Simple with needle sew few stitches the end and the I pull the wire back, in-rolling/inverting strip fabric inside themselves. So finally I got a strip which I sew on each corner. This is very strong but very light-way rope, and it shall be used to tension tent to a pegs.
Step 10: First Look
When inner layer was finished, I just with few stitches connect the layer with bottom and put/rise this in yard to see if all was according Idea and drawing. And as you can see, everything fit together 95%!. Of course, sewing was made by beginner, so small discrepancies are visible but after this first look I adjust fabric to plan and vice-verse.
Step 11: Final From of Inner Part
Last testing of inner part. Top is marked and shall be cut of and finished in sewing machine. So, tomorrow final sewing and assembling inner part. And then on outer layer....
Step 12: KPteepee Final
Well, a day arrived and a rise up the tent. This is a double wall tent. I rise it up or down in 4 minutes.
Total fabric weight: inner part with bottom 932 gr + outer layer 623 gr.
Tent rolled for transport : pack is length 30 cm x 17 cm.
From begging of work till finish I spent about 7 days 2 hours a day.
Price depend on the material but compared with similar commercial tents range 300/500 US D. I got mine for about 90 US D.
It is possible to use zip connection between inner part and outer part to for separate use according warm or cold weather,
but I sew it fixed to each other.
I like to be warm. Always. Especially on mountain top.
This was made for me.
You can make your own. For you. Good luck!
We have a be nice policy.
