Embroidery Stitches On A Border?

I decided to go through my PIG and UFO projects and pulled out my embroidered quilt.  The plan was use my machine and embroider down white borders in a matching design.  It never happened and I ripped out the borders several years ago.  I love the quilt and was trying to figure out what to do with it when I remembered my Ruby has "Omnimotion" stitches and checked out my options.

I started to work on two different stitches and ran out of bobbin thread on the second.

Couple of stitches I was looking at:

Only concerns are keeping the design straight and starting/stopping when I run out of bobbin thread.  Not sure what I should do about borders.  Maybe just stuff it back into the closet for now.
