| 20100192823 | Color pin counting system - The Color Pin Counting System allows needle workers who stitch by hand, and are working on a large design (with 32 to 40 threads per inch) to start and maintain a method of keeping track of threads. The method utilizes 10 pins with jeweled or colored tops. Each pin represents ten linen or canvas threads. After outlining the design area with basting stitches or a marking pen or pencil, one can easily count the threads in the design to find a starting point for stitching. The Color Pin Counting System solves the dilemma of losing place. The primary advantage of the invention is to allow a needle worker to complete a large design while keeping track of the many threads. | 08-05-2010 |
