Scarf is curling

[tjdanzig]

I just started knitting. Yesterday I learned to purl. Excting, but here's my problem. I started my scarf with knit one stitch purl one stitch. Then my friend suggested I use that pattern as the bottom of the scarf and start knitting one row then purling one row. So after about 10 rows, I started that. Here's the problem, my scarf is now curling and I hate it. Is there a way to stop the curling, or to fix the curling after it has begun? I hate the thought of ripping it out, so if there is a remedy, I'd love to learn it.

Thanks for your help.
