1) your choice of jars or plastic bottles, I used both. Here are the bottles two of which have water and food coloring in them.
2) Food color of your choice and or shampoo or dish soap.
3) Label for your bottles. I chose scrapbooking paper I purchased at hobby lobby for $.59
4) mod podge, you can pretty much purchased this at Walmart or your local craft store.
5) get creative this part is up to you to add any additional crafts to your bottles. I used Moss, plastic spiders, that I purchased at the dollar store, I also used hot glue and dark red acrylic paint.
So first thing first wash all your bottles and let them dry. If any sticky residue from the last labels you can use goo gone. Nexts choose your label, if you're using scrapbooking paper then it's time to pick and cut. Once you cut out or chose your label position the label over your bottle and find a perfect spot. Now pull out your much podge, apply the much podge to the back of your label and paste then apply the mosh posh over your label to sell it. If you are done you can add food coloring and water. If not get creative. I used moss over one of the bottle and a round the label on another. Hot glue works best for applying the moss. I also play spiders in the Moss and in one of the small bottles. For the other bottle I used hot glue and let it drip all around the rim and down the bottle. After the hot glue dried which only takes seconds I then took dark red acrylic paint and a brush and painted over the hot glue to make it look like blood dripping. Can fill the bottles with spiders, bugs, glitter anything that will fit and you like. Once you're done decorating your bottle it is now time to fill it with your choice of liquid. For two bottles I chose water and food coloring. For the two small ones I chose not to fill one and the other one I put spiders and clear shampoo.
