Sidetracked

I started off doing a better job this morning staying away from the computer, but got side-tracked by the Make It and Love It blog while looking for ideas for making water bottle straps/carriers for the kids to use on our summer adventures and outings. This one looks great too. Although something more like this is what I had in mind (and more likely to be made as it is simpler). Have you made something along these lines for carrying water bottles? Any recommendations or suggestions?
