Rebecca is good if either you fit into the small size range of the patterns or know how to expand them for larger sizes. I think the patterns are very cute, but since I don't fit into either of the above categories, I just browse them until I can actually use them. A friend of mine LOVES Rebecca - but then again, she is a skinny minnie and a much more advance knitter than myself.
I voted for Interweave. There's just something about the styling of the magazine and the patterns that are in there that I prefer to the Creative Knitting or Easy Knitting zines. There's generally not much in those that I would wear. And, yes I'm a snob, but I prefer a magazine that isn't filled with Lion Brand ads for ponchos. I will pick up one of these from the store if I see something I like - like a recent one had a nice sock section, but I only subscribe to Interweave right now. I will soon subscribe to Spin Off, but that's for spinning.
