Whether your interest leans towards the items themselves, or the advertising that was displayed on many of them, you are sure to encounter something you will want to collect in this varied field. Thimbles, sewing kits and pincushions with advertising, sewing boxes and darners, buttons and button cards, needle threaders, and even items such as skirt markers and hooks and eyes. Threaders are often made of plastic, tin, brass, even wood, so keep in mind these are just a few examples of many different threaders. Some are fabric, others ceramic or glass, crocheted, knitted, or metal.
Some pincushions are both cushion and tape measure.
Almost every old sewing box had at least one fabric one that resembled a tomato. Animal shapes were popular and one that I remember was of a sitting black poodle, approximately 5 tall, made of ceramic with a fabric cushion on his back. Early plastic models, from the 50 s, are highly collectible, especially if you are lucky enough to find one intact, with no chips or cracks, no discoloration as early plastic was prone to, and as they were often made of more than one piece, all pieces. One I recall is approximately 6 tall, of a standing lady in a dress. She is made of three separate pieces.
