Ok, here's what I do, when I get to the end of wrapping, I give it a wrap, then pull up and forward with the hackle pliers, I then slide my scissors down the hackle from the end part just b-4 the fly where i had wrap, I snip it off, then I use the end of a ink pen to just barely push back on the hackle and let the thread slide off the end of the ink pen with a couple of half hitches,, I try to be careful not to let the pen push to far back at this time too cause I don't want the hackle to be pinned down pushed backward, then I just pull back the hackle a little with my fingers and finish the head. Maybe something in this can help...
