Water bottle carrier

Well, I've become quite the craftster this month, mostly out of a need for gifts. Here is a water bottle carrier I made. I have shown it with the water bottle outside, just so you can see the groovy lining. The outer fabric is denim. There is a layer of quilting insulation between the denim and lining...not sure how good this insulation is...I will have to make one for myself and find out. Link to a tutorial here.
