Patterns for cygnet yarns cottony DK

I’m looking for a womens slouchy jumper or Cardigan pattern in the above wool, if anyone knows of one. Thanks

You can look up the yarn on Ravelry and see what projects have been worked in the yarn. For your yarn, there aren’t so many and only one sweater.

Click on the right hand side of the page and you’ll see all 12 projects.
You can do an Advanced Search on Ravelry for DK weihht yarn and a sweater which will bring up many more choices.
Cygnet Yarns also has a website with a link to patterns that might help.

I always use cotton yarn, I find a pattern for the yarn weight I want to use, in your case DK/cat 3. Sometimes you might have to adjust the needle size stated in the pattern to achieve the correct gauge but that can happen with any pattern.

Thank you.
