Fimo Soft and Fimo Professional are both oven-hardening polymer clays by Staedtler, but they feel different while you work with them. Fimo Soft is softer, smoother and easier to knead. This makes it very accessible for beginners, hobby makers and creative projects where you want to get started quickly. Fimo Professional is firmer and more compact. It needs a little more preparation, but gives more control for fine details, clean shapes and professional techniques.
The best choice therefore depends not only on your experience, but especially on the type of project you want to make. For simple jewellery, decorations and creative hobby projects, Fimo Soft is often ideal. For miniatures, cane techniques, realistic figures, clean patterns and highly detailed work, Fimo Professional is usually the stronger option.
Fimo Soft is a good choice if you want clay that is easy to knead and gives quick results. It becomes soft quickly in your hands and is pleasant for beginners. It is also practical for workshops, creative afternoons and hobby projects, because you spend less time conditioning the clay.
For jewellery such as earrings, pendants, beads and charms, Fimo Soft works very well. You can mix colours easily, cut out shapes and create patterns. Because the clay is soft, it is also suitable for people who do not want to use much strength while kneading. Keep in mind that softer clay can pick up fingerprints more easily and may deform slightly faster when working with very fine details.
Fimo Professional is designed for makers who want more control. The clay is firmer and holds its shape and details better. This is especially noticeable with small parts, sharp edges, thin lines, fine textures and techniques where the clay should not deform while cutting or modelling.
This clay is popular with experienced hobbyists, artists, miniature makers and jewellery makers who want a clean finish. Fimo Professional is also suitable for cane techniques, where patterns are built inside a roll of clay and then sliced into thin pieces. Because the clay is firmer, patterns remain clearer and more recognisable.
You can use both types for jewellery. Fimo Soft is ideal for beginners and for jewellery with simple shapes, colour blocks, marble patterns or cutters. Fimo Professional is better when you want very clean earrings, fine details, sharp edges or repeatable shapes.
If you make jewellery to sell, Fimo Professional can be interesting because of the control and neat finish. If you mainly create for fun or like experimenting with colours, Fimo Soft is often enough. Many makers combine both types: Fimo Soft for easy base colours and Fimo Professional for precision work.
Fimo Soft and Fimo Professional can be mixed well. You can lighten colours with white, darken them with black or create custom shades by combining basic colours. Fimo Professional has a system that is useful for precise colour mixing, while Fimo Soft is very easy to handle.
If you want glitter, metallic, transparent, granite or other special effects, you can add Fimo Effect. This is especially useful for jewellery, pendants and decorative projects. Always test new combinations with a small piece of clay first, so you can see how the colour looks after baking.
Both Fimo Soft and Fimo Professional are usually baked at 110 degrees Celsius for about 30 minutes. Always check the packaging for the exact instructions. The final strength depends on temperature, baking time, the thickness of the piece and its shape. Thin parts remain more fragile than compact shapes.
Let your work cool completely before sanding, drilling, gluing or varnishing. Right after baking, Fimo can still feel slightly flexible, but it becomes firmer as it cools.
Choose Fimo Soft if you are a beginner, want easy handling and mainly make jewellery, decorations or creative hobby projects. Choose Fimo Professional if you need more detail, shape stability and control. For many makers, a combination of both is the best solution: Fimo Soft for easy handling and Fimo Professional for precise work.
