I really wanted to make that free Berroco sleeveless top pattern named Marla but I would have had to buy the Pronto yarn to knit it. Sigh. I have other yarns to knit. Knit it for your daughter, I am sure she'll love it as much as I would have.
I just finished the garter top and love it! http://www.berroco.com/226/226_photoview_pv.html I made my longer as no one wants to see my belly (10 balls)! I think it would be great for a 20 something year old. The yarn has lots of stretch (more width than length, I found) so don't make it on the large side of what she wears. RoseM
