I would look into an 'in the hoop' bag. My favorite site for these is MooseBStitchin:

As far as a saying, how about something like, "Rose, keep blooming!"
Whatever you choose to do, I would seriously consider purchasing a second hoop in the appropriate size. YOu can have one in the machine stitching, while preparing the second one to go right away. If you go with an in the hoop project, you can have 2 going at the same time. Sew first color on hoop 1, back design up and sew 1st color on hoop 2. Often, you will need to trim or add fabric so having 2 hoops going really speeds things up.
