You can get the stuff at a garden store. It is white pellets and it is what is used by florists. They put it in floral arrangements. It puffs up and retains water. It doesn't take much for it to expand. I can get the exact name if you need it.

Soil Moist. It can be found in the garden center. I found mine at my local True Value.

Went to Hobby Lobby today - bridal was 1/2 off. They had Crystal Accents (the stuff for the neckcoolers) on sale. Large jar (makes 6 gallons) was $9.99 ($5), small packets were $2.99 ($1.50.) I got the last large jar. She said they had a run on them and they were selling like crazy. If you live near a Hobby Lobby, you might check it out. Bridal Department.

Could you please tell me what helmet coolers are and how to make them? Thank you very much

Thank you for the tute on the kiss. I did several of the ties for my son and his buddies when he was overseas, but I had never heard of the Kiss but now that I have I will have to make some of both the send to his buddies that are back over there again. Thank you again for the pattern.

What is the Kiss?

A KISS is a circular “beanie” which can be worn under a helmet. They serve as a type of cooling device and are often referred to as head coolers. Though our focus is to make these for our troops serving in desert environments, they can be used by anyone. These will also work under a ball cap if you cut them slightly smaller and use even less crystals, and if the ball cap has mesh for air circulation. They are great for farmers, lawn mowers or anyone who works out in the heat all day. Kisses can also be heated in wintertime and used as a reusable hand warmer.

DIRECTIONS FOR MAKING A KISS
1. Cut two 6 1/2—7” circles.
2. Seam around the edge using a 1/4” to 1/2” seam allowance, and leave an opening about 1 1/2” to 2” for
turning right side out. (You can also use a serger or tight zigzag and NOT turn them.)
3. Turn right side out, no ironing necessary.
4. Fill with a very scant 1/2 teaspoon of crystals.
5. Close by stitching on the outside to close opening, encasing a soak tag in the seam. Soak tag should read:
Soak in water for about 20 minutes then place in your helmet for a cooling effect.
6. Hydrate the first one and see if 1/2 teaspoon is too much or not enough. The KISS should puff up about
1/4” to 1/2”
7. Adjust amount of crystals if needed. Better too few crystals as too many will make it difficult to snap the
helmet strap closed.
Place finished KISS in a plastic bag, which can be used for hydrating and include this or other personalized KISS label.


Remember when you were a child
At night safe in your bed
When Mom would tuck you snugly in
Then kiss you on the head.
Well, here’s a little “kiss” for you
It seemed the perfect name
It’s safety that we wish for you
So now, we do the same.
Just soak this “kiss” in water
For 20 minutes or more
Then place it on your head
To cool you off for sure.

I googled it and found it, it only takes one eigth of a teaspoon,, Hard to believe but it works,
