Will Paton's Shetland Chunky Cardi Look Good After Blocking???

[Arielluria]

I just finished my first top down cardi, it was super to have it all done without any finishing needed. It's the Sunkist Cardi

I WAS making it for myself but it turned out small so I decided to send it to some of our church missionaries in Kiev, Russia, for whom our church is knitting stuff anyway. Someone smaller or a teen might like it.

I used Patons Shetland Chunky which I got on clearance at Michael's for $2/ea. which made this about $6. I love a deal! You can't really tell but it's a really nice chartreuse color.

So I've never blocked this yarn and I wonder if the curling will diminish and I'm toying with adding some vertical ribbing for buttonholes instead of leaving it open. Not sure. Any ideas on how to finish this would be appreciated. I'm afraid to go the ribbing route because I wouldn't know what to do when it comes to the curve (where markers are), I'm sure just picking up stitches and making the ribbing wouldn't be enough.
