make any fly weedless

The Aug-sept issue of Fly Fisherman has a blurb, where basically you leave the tag end on your clinch knot long and thread it back thru the hook eye. I haven't tried it, but 2 things make me question. First, the author specifies mono, it seems the tag would be a visible deterrent to the fish. Second, "choose a tippet that has a similar diameter to the hook". That sounds like a big (oversized?) tippet.

So, do you think this will work? And, do you have a in the field (on the fly?) way to make a weedless fly?

Ill just go ahead and hijack my own post, but the same issue has a DIY travel tube, which is exactly how I make a rod case for my TFO rods. I know some on-line shootouts take TFO to task for the lack of a rod tube, but this is cheap and ez, and it helps keep the cost of TFO rods down. My house came with a deactivated whole house vacuum so I have a lifetime supply of rod tubes..... Just take a plastic tube, pick up a couple end caps (peanut butter jar tops also work), and go fishing...........

Since I do not get Fly Fisherman magazine, this thought may have no bearing on your question, but, is the article referring to flies for bass? If, so, they are not as shy of tippet material as trout. There are bass jigs with huge weed guards and the bass pay them no mind. Just a thought and nothing more....
