rerooting thick yarn

Any advice for plugging 12ply yarn?

For the front row and parting: With a big needle, place a yarn plug once every three plugs then go back with a smaller needle in your reroot tool and pull yarn from your big plug into the left and right holes you left empty. For the inner plugs: place the end of your yarn piece against the hole and push it in with the big needle, snip with tiny scissors if any sticks out. That way your working with half size strands and it looks less sparse (other option: root in folded yarn as usual then go back and cut off half of each)
