About K1C2

Owner, Susan Levin

K1C2, LLC was founded as a partnership in 1996 by Susan Levin and Gloria Tracy. In 2000 the company became a California registered LLC.  Since 2008 Susan Levin has been the sole owner of K1C2.

The partners wrote several books for crafters:

Crochet Your Way (Taunton Press)

SHOW ME HOW: Knitting (SoHo Publishing)

SHOW ME HOW: Quilting (SoHo Publishing)

In 2008 Levin wrote

ColorSense: Creative Color Combinations for Crafters (SoHo Publishing)

  Susan Levin has degrees in art history and graphic design. Her professional experience includes department store merchandising, graphic design, and corporate marketing. She has had her designs and articles published in major craft magazines and she co-authored a series of articles in a trade magazine titled “On Target”, an educational series that focused on the challenges that shop-owners face related to customer service, pricing and consumer education.

Product Design & Development

K1C2 began business by developing proprietary products – YarnBras® slipcovers for skeins, Spool Stockings® slipcovers for spools, MagniClips® clip-on magnifiers, PageMinder® book holders and Knit One, Crochet Too® Patterns and Yarn.

Recognizing crafters’ need to understand and use color successfully, the partners invented and patented a “Device for Determining Color Combinations” which is marketed as the Rainbow® Pick Point and Match® Color Selector. This innovative product was quickly joined by companion products -- the Rainbow® Tonal Color Selectors and the Over the Rainbow® Masking Tools.

K1C2 also develops products that are licensed to other companies. Two notable products in this category are Adornaments Fun Fibers and the 123D Paper Crafting System.


In 2013 K1C2 purchased The Happy Brands, a company that specializes in gifts  and accessories for crafters. The products are marketed under the Knit Happy®, Quilt Happy®, Stitch Happy® and Crochet Happy™ brands. To support this new endeavor, the Stuff You Love domain was launched to sell the entire range of K1C2 products.
