Abstract

Abstract A thread dispenser for string art includes an elongated frustoconical tubular handgrip having front and rear ends of respectively relatively larger and relatively smaller diameters. A wire projecting radially from the rear end of the handgrip has a sinous bend intermediate its length serving as a land for a spool of thread and a straight end for carrying the spool. A notch through the wall of the handgrip at a point intermediate its length has opposed intersecting cross sectional and rearwardly inclined surfaces. Thread from the spool is trained through the notch and out the front end and the thumb of the operator gripping the handgrip in the nature of a pen serves as a brake by pressing the thread against the rearwardly inclined surface.
