The one where I use Insul-Shine

Carrying on from yesterday's post where I use Insul-Bright, I am now using Insul-Shine.

I got a free sample pack of this at Festival of quilts - Thank you The Warm Company! (see this poster that they had in their stall offering a freebie if you email them)

However, there aren't a lot of suggestions on the internet: Mr Google has very few ideas a to what exactly we should DO with Insul-Bright, so I though'd I'd have a go myself.

It keeps hot things hot, and cold things cold.  I have a yard (which is amazing, thank you Warm Company) but I could have as many as 12 ladies on Friday, so I cant suggest lunch bags or similar as there wont be enough to go round.

So I thought I'd made a cold water cozy.

I cut a rectangle 6½ x 9 inches to go round the bottle, and then had to dust off primary school maths to work out the circumference of the base:
C = 2 π R which ends up with R = 1.43 and therefore C = 2.86

So I cut a 3" circle from the spaceman stuff, and cut the same again from fabric. The Insul-Shine is already attached to wadding so it's fairly simple.

Join both rectangles into a short fat tube right sides together (ie two rectangles = 2 tubes) (you could leave an opening for turning in the Insul-Shine tube)

Attached circles to the base of each (RST) and remember to say Thank You to the person who invented Wonder Clips!

Turn the outer tube right sides out, and tuck it into the inner tube (if you want a strap now is the time to add it)

Clip the top edges together but just stitch half closed

Turn through the hole and arrange (the bottle may help push everything into place)

Fill with a bottle of frozen water and admire!

(I'm testing mine now to see how long it keeps the water frozen.  If it's too good at its job I'll freeze HALF a bottle then top it up with cold water when I go out so I'll have cold water to drink straight away)

  1. Haven't heard of Insul-shine - off to email just in case they are giving it away in the states.

  2. Haven't come across Insul-shine either Benta, was it easy enough to get through the machine?

  3. I too would like details on how to actually sew the stuff.

    1. Absolutely no problem stitching it at all: imagine a silvered paper yoghurt lid (muller corner?) but thinner, with a bit of wadding /batting on the back!

      (Sorry anonymous, I can't reply by email so I hope you find this reply)

    If I am going to use it for the inside of a lunch bag, Will it still insulate if I have a fabric liner too?

    1. Hi mytbags4u, I couldn't find a definitive answer, but I would imagine that's it's the properties of the shiny stuff that insulate and therefore it will work even if there is a lining. If it was refelecting light it wouldn't , but heat would just go through the lining and be bounced back when it hits the silvered stuff???? Sorry, but hopefully it's an educated guess!!!!

    2. As it turns out, I did a test! I made 2 identical bags, both using insul-shine. One had an inner lining, the other did not. They both kept my bottle of ice frozen for 12 HOURS!!! There was no difference whether the bag had a lining or did not. I LOVE this stuff. It is easy to sew on/with too.

  5. could you use it for a window shade, ?
