In a piece of cardboard cut a square (size 6 inch) and marks the exact center.

With the paper scotch unite the paper towel roll with part of toilet roll.

Cut 2 inch of the toilet roll in strips and flatten out.
With the paper scotch unite the strips with the cardboard square

you must cover the entire square and all toilet roll to make a strong foundation..

With vinyl glue and toilet paper cover all tube and square. Once dried becomes hard and more resistant.

To make it more stable I decided to cover a second time with piece of paper and glue.

I liked the effect of the newspaper but can be painted with acrylic colours or be covered with fabric.
