Pete C used his keyboard to write :
Already have a fairly large 20" box fan, so bought 8 cheap and
cheerful hand towels, wet them well and hung each one over a hanger in
front of the fan, with a gap of 2" in between.

Noted that the side nearest the fan dries quickest, so doubled up a
third of the towel on this side (so half with two layers, half with
one)

Try hanging lower edge of the towels in a tray of water, capillary
action might be enough to draw the water up.
