ABSTRACT:
A spool for thread with a self contained bobbin holder. A contrivance consisting of a spool with a self contained bobbin holder is described. The invention is based on the fact that the core of the spool is projected beyond the edge of the spool creating a protuberance which functions as a receptacle for the bobbin, allowing the contrivance to temporarily store the mated spool and bobbin for quick and easy retrieval.
