Reflectix - how to you attach it to your kettle?

[cgriffith]

I use a single layer of reflectix during mash only to hold consistent temp. I have slits cut out for handles. Wraps around kettles once and overlaps just a bit(about 8 inches). Then I use an old inline skate shoestring around the circumference tied to hold in place. Takes all of 30 secs to put on and take off. When not using, I roll up and use the same shoestring to keep rolled.
