The first step is to get the bottles. You can use either plastic bottle recycling or glass bottles for your message in abottle recycling invitation. We purchased glass bottles for our invitations as we only needed 25. These came with the corks and we bought mailing boxes with them. You can also get 8oz. plastic bottles in bulk, if you want to save some money. The plasticcut wine bottle crafts also come with corks, but you don't need boxes to mail them

If you sand in 5 lb bags, each bag will fill about 150 bottles with about 2" of sand. Or, if you are really determined, you can head on down to the beach! If you do want to "dig your own," be aware that it might be too damp and will stick to the sides of the water bottle crafts. If this happens, dry the sand in an oven before filling the bottles. The sand will have a nice powdery appearance, rather than being wet and clumpy

MAILING YOUR BOTTLES To send the plastic bottle recycling through the mail, all you have to do is secure the cork. The postage on theplastic bottle decorati with less than one inch of sand is around $1.64 - without sand it's only $.60. We mailed our actual invitations which were the glass bottles that came with boxes. We ended up putting iridescent blue tissue paper on the bottom of each box and surrounding it with that crinkle stuff (like easter grass but nicer) to help protect the glass in mailing. I taped each box shut before I went to the post office. I recommend doing this only because otherwise they will use the ugly blue and red postal tape and ruin the look of your boxes if you let them do it. I used the wide, clear packing tape. We paid right around $5 per box, we delivered all those near to us. Also, go to the post office and request either that they print out the postage on small labels (ugly but useful) or see if they have tropical varieties of stamps available.

Another popular crafting medium is the use of products made from recycled plastic bottles caps. Once again you can make just about any of the previously stated crafts withways to recycle plastic bottles caps. You can make a brooch out ofwater bottle projects caps too; you could glue a picture or special item to the inside of the bottle cap and then glue a small safety pin to the back of the water bottle art cap.
