Great looking. Very nice job.
I never have luck writing in the middle of the bag. The moisture from the cold links keeps the surface damp. Also when the freezer frosts up the outside of the bag you won't be able to read it.
I always write on the top seal, that about 1 inch of bag material left after you seal the links inside. In fact, I do an extra heat seal near the top, and it makes a nice flat "label" area to write on. I date it, and identify what's inside.
I don't think sticky labels or tape will still be sticking on them after awhile in the freezer, especially if someone shuffles them around a time or two.
