I purchased a roll a few months ago and have found it to be great. I have not had trouble pre washing it like a PP. I cut it a bit bigger then I need, put it in my washer then in the dryer to preshrink. I did have the last one rip a bit near the edge, I just used a wide zig zag to repair the hole, just like you would if you were piecing some batting together.
FYI- it is listed as 90 wide but mine is 94 wide, nice to have a little extra.
Do you have a link on the website? I was waiting for another sale to pick up a new roll but I can only find the package/pre cut version on the site.
