Roundabout leaf tank

I want to thank lilikoiknits for giving me the invitation to join this site. I love Norah's designs and can't wait to do my next project, the Ram's Horn Jacket. In the meantime, I just about finished my Roundabout Leaf Tank , I need to connect the shoulder straps to the body of the tank and was wondering the best sewing method to use to do this. I would greatly appreciate any help anyone has to offer on this. I look forward to your comments.
