I use the DMC Floss to tie my quilts. I use a regular needle with a big enough head. Bigger the needle, the better. Blunt tip won't work at all b/c you have to go through all the layers. I drop it down through all the layers, move it over a little and bring it back up. Then I double knot and cut excess. Becareful that you leave some string behind so your knot doesn't come out. Just tie a knot as if you were tying your sneakers. That is what I do, just w/out the bow. I tie most of my quilts. It does take a while, but if you do it while watching tv or something it makes the time go by faster. With 865 squares, you will have to take lots of breaks! Good Luck!
