Are you a member of Rav? If so, there were 32 posted projects of this bag and lots of comments. Various ways of dealing with the handle (some covered, some partially covered, etc).
If not able to access Rav, another non-crocheter opted to whipstitch the handles. One did a seed handle. (Pics attached.) Suffice it to say, no two are alike so you can personalize it however your skills allow.
