As to Shrinkage.
I boil washed the first bit yesterday evening and tumble dried it.
Before it was 47 wide and 82 inches long.
After it was 46 3/4 wide and 80 1/4 long
So yes , negligable shrinkage across the width , and probably not enough in the length to worry you if you have enough to work generously with in the first place . ( Last time I barely had enough , so the shrinkage meant I had to put other facbric the round the bottom and 'hide' it with a fringe)
The fact that I was inconvienienced by this probably meant that in my mind I have remebered it shrinking more than it has.
The internal ('weft' ? ) is of a different more 'plastic like' thread than the red and white ( 'weave'?) which would seem to account for what shrinkage there is being worse along the lenght of the canvas ...the width remained virtually unchanged.

So yes , we are all talking about the same fabric , wherever we source it from. As Les says It does not make the booth too hot to work in ...the proper canvas that he mentions ( presumably the thicker , more dense stuff that deck chairs are made from ) ..would be hoter in use ( as well as very heavy as Les says ).
I guess if you only sponge down your cover ..or wash it in very tepid water , then you wouldnt get any shrink at all.
But what my boil washing has done, is transform a material with the texture and handling of thin artistes cardboard , into a managable soft fabric that folds easily and is easy to work and sew.
Before it didnt so much 'fold' as 'bend'.
I guess if you are having your cover made for you , then that is not an issue , as presumably the awning companies have big machine tables for laying out work while they sw it.
I know I could never sew a booth cover with the acrylic canvas as it arrived ...I would need a huge amount of room and a couple of helpers to 'support' the bulk of it while I tried to get it through the machine.
Boil-washing it means that it is no more awkward to handle now , than say sewing a set of living room curtains .

So have a cover made , or sew it youself? ..I guess you pays your money and makes your choice !
