help!

I'm designing a couple of the presents that are on my to-make-for-Christmas (this Christmas too - I know, I'm crazy...). Anyway, one of them is the sweater that I'm supposed to be knitting for NaKniSweMo (which totally stalled out about a week and a half ago) and the other is this scarf. (Sorry for the non-ravelrers but I can't risk letting the intended recipient see! If you aren't on ravelry and you aren't a potential knitted-gift receiver, email or comment and I'll let you in on the secret via email!) What I need help with is: do you see the patterning? Do you have any suggestions / comments / constructive criticism? If I decide to write the pattern up for sale on etsy (or through the blog or LYS) would you be interested in being a test-knitter?

And now, some knitting that I can share (it's for my Nana for Christmas, but she doesn't own a computer, much less know how to use one!):



Pattern: Wisp from Knitty Summer 07
Yarn: Rowan Kidsilk Haze in a grey-ish colour (I lost the tags so I don't know the exact colour # / name)
Needles: ChiaoGoo US 7 circ
Mods: None so far, but I don't think I'm going to add buttons - I want it to be more of a scarf / light shawl, and I don't see my nana fiddling with buttons and mohair...

Thanks in advance for anyone who emails / comments (on ravelry only please... don't want to give anything away!) on the design dilema!
