What simple tools can be used to create these artistic shapes?

As an AI language model, I do not have personal experiences or preferences, but let me give you some insights.

There are several simple tools that can be used to create artistic shapes, some of which include:

1. Pencil and Paper: This is the most basic tool for creating artistic shapes. It incorporates sketching and freehand drawing of shapes, producing different patterns.

2. Ruler and Compass: A set of ruler and compass are commonly used to create geometric shapes, such as circles, triangles, and rectangles.

3. Stencils: Stencils come in various shapes and sizes and can be used to create identical shapes repeatedly. They can be custom-made by creating a pattern over a paper, tracing your desired shaping with scissors, pen, or cutter.

4. Cutters: Cutters can be used to create intricate shapes by removing or cutting different parts of paper or other materials.

5. Screens: Mesh screens can be used as stencils to create shapes repeatedly on an art piece.

6. Computer Applications: There are several digital tools available with simple user interfaces to create artistic shapes digitally. These applications come with several shapes and patterns that can be customized by users. Examples include Adobe Illustrator, CorelDRAW, and Inkscape, among others.

There are various simple tools that can be used to create artistic shapes. Here are a few examples:

1. Pencil: Drawing shapes with a pencil is one of the most basic and versatile methods. You can easily create straight lines, curves, and geometric shapes by varying the pressure and angle of the pencil.

2. Compass: A compass is an excellent tool for creating precise circles, arcs, and concentric shapes. It consists of two arms, one holding a pencil lead and the other acting as a pivot point.

3. Ruler: A ruler is handy for drawing straight lines and measuring distances accurately. It helps in creating geometric shapes such as squares, triangles, and rectangles.

4. Protractor: A protractor is used to measure and draw angles. This tool is essential for creating shapes involving specific angles, such as polygons or sectors.

5. Stencils: Stencils are pre-cut templates with different shapes. They allow you to easily trace shapes onto your canvas or paper. Stencils are available in various materials like plastic, metal, or paper.

6. Templates: Templates are similar to stencils but are usually made of rigid materials such as plastic or metal. They are used for repeated and consistent shapes, like circles or squares, and can be traced or used with a cutting tool.

7. Compass Divider: This tool is used for dividing circles or arcs into equal parts. It consists of two arms with adjustable spacing and allows you to create precise divisions or patterns.

8. Brushes: For more free-form shapes, brushes of different sizes and shapes can be used with paints or other mediums. They allow you to create organic and flowing shapes with varying thickness and texture.

These are just a few examples, and depending on your artistic style and preference, you may find different tools more suitable for your work.
