I decided to make one instead since this one also seemed a bit too course, so I went to a local fabric shop and asked about voile. For some reason all the different versions of 'voile' they had were made out of cotton
So I asked about polyester and was directed to something called Bridal Chaffon. Pretty sure they make wedding dresses out of it if I had to guess, anyway, $14 later I had enough to make 2 bags large enough to completely line my 60L kettle. I took a picture beside a ruler and zoomed in nice and close, this stuff has about 42 threads per cm. I have done 1 BIAB with it so far and it worked beautifully, seems to drain as fast as my other bag did (which had around 28 threads per cm) but I now have about half the trub in the bottom of my kettle as before. One thing I notice is its not as stretchy as my store bought bag, but didnt seem to affect anything.
Anyway, just thought I would throw this out there since I haven't heard this material mentioned anywhere for BIABags...
