I got the flower fabric for the outside and the plain fabric for the inside. From each of the fabrics you will need 1 (one) piece approx. 22'' long by 11'' wide, so one from the flower fabric and one from the plain.
Take your plain fabric, and fold it long ways. This does not have to be perfect! Notice, mine is definitely not!
You are going to sew the long side first. Followed by one of the short sides, notice I said ONE of the short sides- NOT BOTH. This will sew the bag shut and defeat the whole purpose! =)
Now turn your bag inside out (so the seam is on the inside).
Now take the outside fabric, and turn one of the short edges down about an inch, and sew.
Take your fabric, and fold the fabric longways, just like the other bag. This time make sure the outside of the fabric is turned toward each other. You want the inside of the fabric on the outside, so we can sew it then turn it inside out.
And here it is! The final product! Pat yourself on the back for a job well done!
And another way to reward yourself right now, is to heat this puppy up!
Stick your rice neck warmer in the microwave for about 2 minutes. Make sure you test this our before you give it to a child, to make sure it doesn't get too hot. After 2 minutes, pull your rice neck warmer out of the microwave. It will probably smell like rice, and that's OK! It will be less strong the more you use it. It also may be a little damp feeling the first time or two. This is normal also!
One nice feature of this is that if you need to wash the outside cover, you can just slip it off and throw it into the washer. When it's done, slip it back on and use it again! You can also use this as a cold pack.
I hope you try this out! You will be glad you did!
