Extend the life of your disk. Use a sharp knife to lengthen each slot on your disk. You only need to extend the slot by about 2mm. When you braid be sure to pull the cord into this new section for renewed tension. I only recommend this as an emergency measure because I have found that the new part of the slot is not as smooth as the factory cut slots, which may result in snagging of the cord. However, there are times when you need to get started on something straightaway and do not have time to send off for a new disk. This tip is perfect for those occasions!
