Ditto - made a bunch of long/short ones a few weeks back. The thing I had to work at was to get sufficient coverage around the micron of the black mark: when you wrap it round the dowel, don't do it too tight and leave space between the wraps, then when you brush over with the marker do it a bit forcefully such that you twist the micron over slightly - then you get marker color all round the line - just makes it neater
Likewise, can't wait to try them.
