A spool of thread holder and threading device for holding a plurality of spools of thread, made up of a frame and a plurality of spool thread holders, said spool thread holders further comprising a rod, a base and a wing. The wing attaches to the rod along the axial length of said rod and the rod extends from the base. Each of the individual spool thread holders comprising the multiple spool thread holder, allows receipt of a spool of thread and the wing maintains the spool of thread adjacent the base. The frame is configured for attachment to a quilting machine to allow thread to unspool from each non-rotating spool of thread during operation under substantially equal tension.

A method and apparatus for stitching a workpiece, such as a quilt, is disclosed. The method comprises displaying a predetermined pattern on a display and manipulating the predetermined pattern on the display. The display includes an indicator corresponding to a position of a sewing head relative to the workpiece. The method further includes moving a control handle operably connected to the sewing head to move the indicator relative to the pattern on the display and move the sewing head relative to the workpiece. Devices to practice the method include sewing machines having a sewing head moveable relative to a workpiece and a control handle operably connected to the sewing head to move the sewing head relative to the workpiece, wherein the display showing a pattern to be sewn is mounted relative to the control handle for movement with the control handle.

Presented are a method, apparatus, and computer-readable medium for stitching. The method includes sensing, by a first sensor, a movement of a work piece relative to a sewing head. The method further includes sensing, by a second sensor, a movement of the work piece relative to the sewing head. The method includes determining, by a processor, a translational and rotational movement of the work piece relative to the sewing head based on the sensed movement of the first sensor and the second sensor. The method also includes altering, by the processor, a speed of a reciprocating needle in response to the determined translational and rotational movement.

A sewing frame unit is provided. The sewing frame unit includes a frame support structure; a frame assembly affixed to the frame support structure; a machine carriage assembly mounted on the frame support structure. The machine carriage assembly provides for lateral and longitudinal movement of the sewing machine. A sensor is mounted on the machine carriage assembly or on the frame assembly for detecting a position of the sewing machine.

Vibration reduction mechanism for a sewing machine. In one example embodiment, a vibration reduction mechanism for a sewing machine includes a rotational counterweight and a reciprocating counterweight. The rotational counterweight is configured to be coupled to a driveshaft of a sewing machine and is configured to be rotated by rotation of the driveshaft. The reciprocating counterweight is coupled to the rotational counterweight. A first portion of the reciprocating counterweight is configured to be rotated by the rotation of the rotational counterweight. A second portion of the reciprocating counterweight is configured to be substantially reciprocated along a length of a structure by the rotation of the rotational counterweight.

An insulated composite fabric has an inner fabric layer, an outer fabric layer, and an insulating-filler layer enclosed there between. The insulating-filler layer is a textile fabric with at least one raised surface. One side of the insulating-filler layer comprises a first surface with relatively high pile, including regions of no pile or relatively low pile interspersed among regions of relatively high pile. The other side of the insulating-filler layer comprises a second surface with relatively high pile, including regions of no pile or relatively low pile interspersed among regions of relatively high pile. Interconnecting piles are formed with regions of the relatively high pile of the first pile surface and regions of the relatively high pile of the second pile surface.
