Concrete is among the most popular materials for all kinds of crafts, and pots and vases are no exception. To make this one you’ll need a small and a big plastic bottle. Cut the neck of both bottles, and glue the small one into the big one. Put some silicon glue on the bottom to fix them to each other. Prepare your concrete as indicated on the package and poured it between the two bottles. Two day after, remove the outside bottle. The small bottle inside will stay as your vase container. Cut off the extra plastic in the top of the bottle if needed. Keep reading what to do in the source.
