Hi Gordon, thanks. The magic tool is from: www.veniard.com/product943/section16/petitjean-magic-tool-set and you can see how to use it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ShuWsnX17jk.html
Really like this style Barry, haven’t seen this method before so I’ll give it a go. I’ve been fishing the traditional hackle style midge on a dropper using a larger fly on the point for both a sight indicator and a little extra buoyancy but I like the cdc look. Do you mind if I ask what floatant you use for your CDC patterns? I’m not a fan of anything heavy like Gink where it leaves almost an oil slick look surrounding your fly
