My cured leaf hangs until I am ready to kiln it. A cheap box fan in the shed never stops.
I have saved up a number of very large, colorless plastic bags (~2'x3') from various sources--a trash bag will do. I put the individual crispy leaf (it's all leaf primed) into a large bag, mist it thoroughly with water, twist and close it with a clothespin, then check it the next day. Sometimes I can avoid this step if it has rained for a couple of days. At the point when the leaf is pliable, but the stem is still relatively firm, I strip the stem, then fold and press it to fit my quart Ziplock freezer bags. If you're going to hang the leaf in the kiln, you can just spray it where it hangs, and go from there.
The only reason I stem my leaf prior to the kiln is because my kiln is too small. (Hanging leaf may have some white mold on the stem. Although it's not likely to grow in the kiln temperatures [120-130ºF], by stemming it, the bulk of any mold ends up in my trash, instead of my kiln and finished tobacco.)

NOTE: It is my personal opinion that pressing the leaf (~1-2 psi), and the resulting close proximity of leaf surfaces while in the kiln, has little or no impact on the final product.
