~~PLEASE VOTE FOR ME IN THE BACK TO SCHOOL CONTEST~~

Do you recognize the problem that you want to drink some cold water in the school break and your beverage is warm because of the temperature outside?
Now you don’t have that problem anymore!
If you use this coolkeeper your drink is almost the same temperature as before!

So go get some stuff and make it yourself!

Step 1: What Do You Need?

-One 0,5L bottle
-Fabric size 24x24. (double layer is recommended)
-Needle and thread
-Tin foil (size 20x24)
-Scissors (not on photo)
-Marker (not on photo)

Step 2: Step 1

Put the tin foil in the fabric. (sew it when it’s not double layered)

Step 3: Step 2

Wrap the fabric around the bottle. (you don’t have to tighten it yet)

Step 4: Step 3

Cut the unnecessary fabric at the bottom away so it has the right size.

Step 5: Step 4

Now, look where the fabric meets (like at the photo) and mark that.
Take the fabric off the bottle and sew the fabric together on the mark.
When you are finished cut the unnecessary part away.

Now your coolkeeper should look like the last photo!

Step 6: Step 5

Now, sew the underside of the fabric together so the tin foil can’t fall down.
Make sure you leave an opening for the bottle!

Step 7: Step 6

Now insert the bottle into the cool keeper and… voila!
No longer warm beverage at school!
Awesome idea! Nice design :)
