Trying to make some Whoopie slings using SloBro's thread, got the taper done just fine and started the bury. I've got about 80 percent of the line pulled through but I just can't get it the rest of the way. It's constricting on itself and I can't seem to get it moving. Any advice? I taped the line to the yarn needle but I don't think that's the hold up, more likely the half-inch ends left from the tapered pieces.
