A thread cassette in the form of a cassette-like plastic box adapted for holding two bobbins of thread. Once assembled with the bobbins disposed therein, the cassette cannot be reopened. The cassette casing enables thread therein to be easily and readily dispensed on demand. The plastic box features an integral cylindrical element which fits a standard sewing machine spool spindle. A single-bobbin casing is another embodiment of the invention. The two-bobbin embodiment may be used for supplying thread to a two-needle sewing machine.
