Magenta Scarf

I got a little knitting done today on a magenta scarf. I'm out of acrylic yarn so I'll have to wait until I get some more. It's a nice wide scarf. A silver brooch would look lovely on it. I'm going to use 2 other colors on it. I'll decide which colors when I see what's available at the store. Or if I get home before I get to the store I'll use my existing stash. I really don't have the room to store any more yarn so I'd like to use what I have. And I don't want to move it all again. Not that yarn is heavy, but it's bulky. We bought some of those suction bags to store it in, but then I read yarn should never be stored in plastic. So now what?
