A plastic bottle, for several decades now, has been used by our craftsmen as various devices and materials to create useful and necessary things. And the source of ideas is simply limitless. Ideas for a new application are dictated by life itself.
Containers for umbrellas.
If you need a strong broom, you can make it by cutting the bottom of the bottle, place the neck on the stalk, dissolve into strips (about two-thirds of the bottle).
Stand for charging a mobile phone. Now your phone will not gather dust on the floor.
Containers for tangle. If you like to knit, but you have cats in your house (who constantly play with balls), then these containers will be very useful to you.
Fasten them to the back of your chair and your balls will never get tangled.
Ideas are prompted by life - wisely, beautifully and conveniently.
