INVALID Student Sewing Course


This course 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 sewing course 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.
