I continue to use aluminum electric fence wire. Two leaves back to back, then a finger-width space. A 4' segment will typically hold a single priming of 16 plants--about 32-50 leaves--all from the same bed (same variety). To each wire I attach a Tyvek tag (cut from a used mailing envelope) indicating the variety, year, stalk position (mud, lug, leaf, tip). If the leaf will be tied into a hand, then the tag is tied onto the finished hand with string. The tag follows the leaf to the kiln and then to its final storage. For flue-curing, I use a wooden tag (1/3 of a tongue depressor) with a drilled hole. Once the leaf is out of the kiln or flue-cure chamber, I mark a large red 'K' or 'F' on the tag.
Since the wires are hanging on braided Nylon rope in the shed, I can easily reposition them as needed. I really want to avoid the added weight of sticks, and their relatively fixed lengths.
For stalk-cured plants, I hammer in a nail (in the field), at an angle that serves as a hook. When hammering in the nail, I puncture the Tyvek tag with the nail, so that it stays with the stalk. This tag also follows the stripped leaf.
