To create your water bottle template, print a picture of a water bottle, and cut it out. Make sure the inside dimensions of the cut out are the same size as your basic square template. You can increase or decrease the size of the template or the photo you cut out as suits you. Mine is 2 ¾” square. Trace the shape onto your cardstock, and cut it out. You will lay the card face down on your layout pattern, and temporarily tape it in place. Cover the neck of the bottle with a folded piece of solid colored paper, putting the fold at the edge of the square layout. Follow the instructions to fill in the square.
Once you have your bottle filled in, you can mount it on a card, frame it, or whatever suits your artistic needs.
