Resizing swap partition advice

Looking for some opinions here. I need to increase my swap partition. It's currently 1GB and I'm banging against the top of that on a regular basis (I have 1 GB of RAM, but that's no where near enough... but can't easily add more RAM). I need to at least double the swap partition... or maybe even go for 3GB. I've never had to resize a swap partition before... I assume I have to drop to init 1 to do this. And then use parted with the resize partition start end options? Has anyone done this? Is there an easier way to do this? parted kind of... makes me somewhat cautious.... I don't know my way around it and I'm not 100% confident with the resizing partitions thing in parted. Any advice or suggestions would really help :-) C.
