Faux lags?

 I am getting back into my spinning...and whilst waiting for my new wheel to arrive, thought I would have a go at making these so called faux lags..eg ..rolags. In real terms.  I have some gorgeous Shetland which is very open anyway and could be spun with just a little drafting...but I want to do long draw and create woollen yarn.  So I googled and came across this idea which seems to work well...hope the photos are self explanatory. I used a 20mm knitting needle which has made nice sized rolags.
