Have you always wanted to start your own clothing line?  Then our courses are perfect for you! During these courses you will learn how to work out the creative designs from A to Z. INVALID guides you from sketch to finished product. Together we make high-fashion and high quality clothing.


The sewing courses include all necessary materials such as: Test material, (pattern) drawing paper and haberdashery. Of course you use our sewing and lock machines.

Haute Couture is for everybody!

The sewing courses have a young, dynamic atmosphere. We are working at a fast pace. Characteristics for our culture is the high work pace, the secure mentality and a passionate and inspiring work environment.

We are determined you come away with the skills and confidence to take on future sewing challenges.



This workshop is especially for people who want to work with clothing both creatively and technically. If you want to develop your own ideas or if you have been working around with them for some time, then this workshop is very suitable.


By means of a mood board you will be inspired in different styles. We pay attention to shape, material and color theory. After this, it is time to lay down the inspiration on drawings, also known as illustrations.

When the design is finished we start with the technical part, pattern drawing. During this part you learn to accurately record measurements and then calculate and translate them into a accurate drawing.


When the pattern is finished, a test model is stitched. This is the first step in the sewing technique. 

Does the trial model connect? Then it is time to start with concept development. This is the phase in which the design is worked out in the right fabric.
