I look forward to seeing the garters! The pattern is from a pair in the MFA in Boston. The center was really hard to see. There was some kind of pattern that I couldn't make out other than the initials and date so I gave up on that bit. The quatrefoils are right, though. When I went to find the link for you, I found that the center is quite clear so I don't know if they've improved their picture or if I somehow had some kind of issue looking at it before. http://www.mfa.org/collections/object/garter-one-of-a-pair-121953 Maybe you can fix the design in the center, which turns out to be a bow. I wish I had made my ribbons about six inches longer. There's not much left to tie by the time they've been wrapped around my legs twice. Learn from my experience!

My estimate is about one square inch per hour on cross-stitch. It's just a rough estimate, but it's good for planning purposes.
