Retic, are you referring to the first picture or the second? In the second one, I use longer wicks than that - they down to the deck, back up and flop over along side the coil. In the first pic, you just wrap the coil on the tube, slide it onto the silica then snip off only the amount that you need. After that just keep feeding the wick through for the next coil. Pretty good idea if you can find a thin-walled tube that's small enough.
