Hi not sure if this questions been asked before but im looking at getting an awning - roof only made for my 10ft aluminium van it has the curve roofing (mostly in corners) I've been to a canvas maker who's never made one before. He's going to need my van a few times to get the awning curve right & wants to set it up level with correct pole height etc otherwise he reckons the curve can end up uneven or lopsided. I thought that the curve would be a separate triangular shape panel. My question is for those of you that have awnings that go around a curve roofline in the corners is it just a fully rectangular awning with a slight curve in the corners that attach to van or is there a triangular type corner that goes in the curved are. Sorry I dont think I've explained it very well! I just want a tight fitting awning with no sag in the corner thats attached to thd van or a sag in the annex where poles go. Also the awning will be 10ft by 7ft & I'm looking at having just 3 poles do I need to consider adding another 2 poles on centre of each side to stop it drooping?
And finally ive asked for kedder track as i struggle with the rope on my other awning as its not as stiff as kedder. Should I just stick with rope & make sure its sewn in tight.
We had ours made up as a rectangle but did not have any drop down fringe on it, it is just flat. We use a spreader at each end and three spreaders , four poles along the length. Our van is 15 foot long.

It is a bit tricky getting an awning made to fit a curved caravan, and a lot of awning makers aren’t sure about the pattern to use these days because they are mainly working with straight lines.
As you can see our van also has a curved roof:
The aim with an awning for a van like yours and ours is to have the long edge away from the van sitting flat, and the edge attached to the van curved to match the curve of the van. To do that you basically need to have the edge to attach to the van cut on a curve. I’ve tried to draw it here. It’s very rough, I’m sorry because I’ve tried to draw it on my iPad with my finger.
Ok so the bottom edge in the drawing is the side away from the van. The top edge with the curve is where it attaches to the van. The other sides are just straight. The depth of the curve will depend on the height of the curve on the van.
Our awning is 12 ft long (on a 14 ft 6 in van) and 8 ft wide. We used to have a 6 ft wide awning, but found it wasn’t wide enough to provide sufficient shade and protection. We were fortunate because we still have the old annexe for our van and the awning maker was able to use the roof of the annexe as a pattern.
Regarding poles, etc, if your van is a 10 footer you may find that it is difficult to make the awning the full 10 ft, but it depends on the shape of the van. You’ll see from the shape of our van why our awning could only be 12 ft. Anyway, as you can see we use four poles along the side away from the van, and then also a pole in the middle of each side. With a 10 ft awning you may get away with three poles I think. The span between each pole will be 5 ft though. On ours it is only 4 ft, so there will be a bit more flap if there are only three poles.
We found that we didn’t need side poles with a 6 ft wide awning, but definitely do with the 8ft wide one. Without them, there would be a lot of movement and flap, especially in high winds. We also use the ribs from the old annexe - you can see the lines under the canvas.
Hope that helps? It is a bit difficult to explain, but by all means come back to me and ask questions, or I can PM you my phone number and we can have a chat. As it happens, we will be putting up the awning tomorrow, so if you like I can take a photo of the curved edge which may help to explain it all better.

Hi again Bonzaway,
I’m not sure if this photo will help but it may:
You can see how the extra piece of material in the awning that forms the curved edge which attaches to the roof accommodates the extra height of that section while leaving the bottom edge straight. And the side edges are straight as well.
Hopefully if you show these photos to your canvas person they will get the picture.
Oh, by the way... canvas is made 2 metres wide, so if you want your awning to be wider than that (say 7 or 8 ft) you will need to have a join in the awning from the roof of the van to the outer edge. However, that isn’t a problem. We’ve never had a leak through the joins in any of awnings or annexes.
I've made two canvas awnings for my vans, plus converted a heavy duty tarpaulin to make a wet-weather awning when required. In all cases, the awnings look like this when they are cut to size...
I buy the piece of canvas big enough to do the job without any joins. Usually I get canvas that is 2.2 metres wide, and by the time I've put hems around the edges, it comes down to about 2.1 metres from caravan roof out to the awning poles.
This is how I measure the van to mark out the canvas...
Red line A-B is where I want the height of the outer edge (the poles edge) of the awning to line up with the van. Measure the halfway point of line AB and mark as C.
Draw a line perpendicular from C to top of van roof and mark as D.
Curve of roof will be covered by marking AD and DB on canvas, either side of halfway point...
My awning was cut the same way as DonRs diagram with the corners facing the van curving away to allow for the curve of the roof. It was trial and error as to how much. The "mark 1" attempt was not quite enough so Larrythelarrikin (former forum member who did the job) had to unstitch it and increase the curve/cutaway a little more to get it just right. Result was very tidy with no sag or looseness in the awning at all. good luck Jenno
