Ultra Pima by Cascade Yarns is super soft cotton, great for all seasons!This yarn is much softer than other cotton yarns and does not feel stiff at all. Ultra Pima is mercerized using a different process which makes it so much softer than the other mercerized cotton yarns out there. It's machine washable and ready for wear, but has a pretty, subtle shine and classic cotton simplicity. Use it for summer sweaters and all things baby.
