Knit and Purl (and Curl?)

I picked up a neat colored yarn awhile back (Hobby Lobby, I Love This Yarn, #902 Berries, 100% Acrylic) and decided to make something out of it. I have neglected my yarn stash for so long with all my other crafting going on so one night  I picked up this yarn and started crocheting a scarf. About 50 rows into it decided I really should be practicing my knitting. I actually pulled out all those 50 rows of crochet and started over by knitting. I must be crazy. So here it is 3 evenings later:

I'm getting better about keeping my stitches even...and thankfully getting faster (though it only took me one evening to get this far crocheting the piece). I do have one concern though...the scarf seems to be curling inward as I go.

I'm not wanting a tube scarf so this is a bit discouraging. I have no idea if this is normal or what could be causing it. I'm wondering if blocking it after I'm done would help. I may be pulling out 50 rows of knitting to start over again. But that's okay (I guess). I could use the practice.
