The Canada geese have finally started moulting here, and I've managed to collect a bagful. I use a stainless steel chip bag clip (from the Dollarama; cost: a dollar) that I use to hold the fletches for grinding. I had to adjust the clip by slicing off the rubber parts and twisting untill the two sides met perfectly. For the grinding I use a coarse foam sanding block, but I carefully cut the quill back with scissors first. It's not a perfect system, and it sure ain't fast, but it works for me. Oh, I also use the bag clip to glue the feather on the shaft, too.
