What kind of Handle??

Here is the exterior body of the bag all put together. This wasn't as difficult as one might think. Then again, I kind of made a boo boo with the flower (note to self, don't apply any embellishments until AFTER sewing parts together). Now I need to figure out what kind of handle/strap to make. Any suggestions? I need to have this finished by Saturday. . .so I'm on time constraints here. I was originally planning to do 2 longer shoulder straps. Now I'm considering 1 longer strap & attaching it across from narrow side to narrow side (do you smell what I'm steppin' in?) Then again, should I do 2 shorter tote type straps?
