Here I am putting together a little bank of knowledge of textile theory you may find useful whether you are a student or a hobby sewist. Just use the drop down menu to access what you need to learn about. When I taught Textiles in secondary school, I prepared a wealth of information for my students via power point presentations and a workbook also available from my shop. Just pop over there and download it for free. You can also download the workbook to test yourself.
Now I changed my school resources for the use on the internet. I do not go into great depth, as I would for 'A' level students, but aim to give a good overview into textile practice. From yarn to fabric find out what you need to know to purchase the right fabric for the job.
