My question is ....can you knit with ribbon form the fabric store or do you need to use ribbon yarn?
Thanks in advance!
I'm sure you could. People knit with plastic bags and recycled t-shirts, so why not ribbon. You would just need to check the content and care instructions. Actual ribbon is going to be lighter and probably won't hang/drape quite the same as ribbon yarn.
Yes, you'll need a lot of it though so it may get expensive - ribbon yarn costs much less per yard. Use a large needle, like ribbon yarn, ribbon will knit up at a bulky gauge, even the thin ones.
