What is the difference between hot cut and cold cut?
This refers to the type of knife used to cut your material.
A HOT cut is achieved by using a heated knife that cuts by melting. Materials cut in this manner are usually sealed and will not fray.
A COLD cut is achieved by using a two-piece knife that cuts by shearing. Materials cut in this manner will normally fray.
Some materials, such as hook & loop, may be cut with either method without fraying.
