    Yes, I watched the same vid and came to the same conclusion; bigger lighter reinforcements are better. Also that 90 degree corners are big stress raisers, hence my initial plan for a many sided teepee, i.e. gentle angle changes between adjacent panels. Which means more tieout points, which means less stress per tieout. It's a virtuous circle.

    I want some proper glue too, and couldn't find U-09FL online either. :(

    Looks like it might be loctite 09FL here, but still tricky to get. Ads for other eurathane glues don't seem to mention how flexible it is when cured.

    3M do a flexible urethane adhesive in 48ml dual cartridge for around £25. It seems to be overkill at 2800 Pound-Force Per Square Inch shear strength if @cathyjc can tear the mylar substrate off the dyneema fibres with her bare hands.

    Perhaps I'll stick to seam grip!

    I’ve been looking around and can’t find an answer: How does one bond a cat cut DCF seam? Seems impossible with tape. Are people using adhesive for cat cuts?

    Didn't use cat cut on my DCF mid. I thought what I was doing was adventurous enough as it was. If I made agin I 'might' put a very slight cat cut deflection on the 4 'end seams' ?? - might make a few wrinkles in the taping but nothing much.
    A significant cat cut wouldn't be worth it as the DCF doesn't stretch - and that's the whole "raison d'etre" of using cat cuts eg.on silnylon.

    MY opinion. Ask Colin Ibbotson - he may well argue otherwise.

    Cathy, were all your panels 125cm wide at the hem?

    NO.
    Cannot remember, off the top of my head, what the width of the other panels are.
    The shape was based on the size I wanted for a rectangular inner, + a bit wider for a 'porch' = 125cms.
    Then I "pulled" the sides out to make extra triangle shapes back and front (=extra porch).
    I like a good sized space outside the inner to cook etc. :)
