Making more with your wool

The spinning mill which helps you add value to wool, mohair and alpaca

Advice and Information

Spinning is rather more technical than many people realise so we do as much as we can to advise our suppliers and customers about adding value to their fleece and getting the best results from spinning their yarn.  This page brings together a range of information sheets on various topics from ordering to background information.  Please don't hesitate just to pick up the phone or drop us an email if you have further questions or would like to speak to a real person - we love talking about fleece and spinning ...

We have set each information sheet to open in a new window so that you can easily track back to this page for further help if needed.

We guarantee to return you only your own fleece in whatever form you choose.  So before you decide to place an order or contact us, please look at the files below and download those you need.  Remember, the more you know, the better your questions!  If you're totally new, please also download this glossary.  There is also a film which takes you through the mill processes.

It is well worth keeping in touch by signing up for our monthly Newsletter, which provides regular updates and news - just complete your email address in the subscribe box which appears on each page of our website - you can of course unsubscribe at any time and please be assured that we don't share our contact lists with anyone else.

Fleeces and Processing

  • To understand what happens to your fleece, with images and descriptions at each stage, download our information sheet showing how it is processed;  this is also available en francais and auf deutsch
  • You may also find basic definitions of woollen and worsted spinning and organic processing on our Blacker Yarns wool yarns info sheet
  • Before sending it to us for processing, some customers store their fleece from one shearing to the next.  It will be preserved better and produce higher quality results if it is washed.  This file offers advice on washing raw fleeces.
  • Finally, to add colour (and customer and market appeal) to your yarns, you may consider dyeing and our information sheet explains the effects of different dyes on various bases of fleece shades.
