You guys and gals may want to consider buying one of these if you have a little extra money ($29.00 + shipping). I bought one box of these Kevlar thread bobbins (144) and now have enough light but strong, almost unbreakable line to last lifetime. Each bobbin has 18 yards of material and is nicely wound into a small roll about the size of a US nickel and three times as thick. Fits well in my PSK. By the way do not go crazy bidding, the seller lists these quite often and if you contact her directly, will likely sell you a box at the starting price plus shipping. Pete
