Soft and easy care probably means you want machine wash and dryable? Do you like wool? Are you on a budget? Are you allergic to wool? Will it have cables? Are you willing to shop online? It helps to have lots of information because there are SO many yarns available.
When asking questions ALWAYS post the name and a link for the pattern if you have it.
I think machine washable so a blend would be ok. no cables.
I think I would be open to wool, but i hate to hand wash things. i think my questions is too general. sorry. i just wanted a few suggestions on your favorite sweater yarn and why you like it.
