This is a very, very scarce attachment to find indeed and we know this attachment is expensive. That's because it is quite a collector’s item not just because of how scarce it is to find one (in complete condition with attachment, both spool arms, original box, manual, and tiny thumb screw), but also because of how difficult it is to find one that is working and functional! In fact, several years ago we quit buying this particular attachment unless we could personally sample and test it before selling. After having several come in the shop at high prices that ended up not working properly because of some minute error in precision, we have been leery about buying them untested. This attachment, however, is a consignment sale so we were able to test it and demonstrate it on video -- all for your assurance that this is a working attachment. I was so relieved and overjoyed when I sat down to test it and it stitched so easily and smoothly! I wish they all worked as well as this one!
It is imperative that each upper and lower clamp grip precisely over the thead crossing arms like you see in the photographs above.
The Two-Thread Embroidery Attachment varied in color over the years. Sometimes they would be chromium and sometimes they would have a blackside finish. This particular one is all chromium.
You can see in the antique baby garment how a similar effect was accomplished with the thread weaving in and out forming a wave-like effect.
As you can see in all the samples above that you can use the standard thumb screw, however, it does make it easier (the thread is less likely to get caught) if you have the original teeny tiny thumb screw that would have been included originally with the attachment. It is so tiny that they were not thought to be a thumb screw when tossed into a sewing cabinet drawer. Who knows how many of them have been tossed over the years. Be sure to watch the video above to see what the original thumb screw looks like.
The best thread that I have found to work with is Sulky 12wt thread. It’s a bit thicker than normal thread, but still lightweight enough that the threads actually criss-cross to achieve the decorative effect the Two Thread Embroidery Attachment is so famous for. However, you will have much enjoyment experimenting with all different thread types and styles.
Practice makes perfect! Be sure to use a stabilizer with your fabric, just like all machine embroidery work. After reading through the instructions and working very, very slowly, be sure to start out by practicing with straight lines. As you gain more confidence, use a traced design and work with curves and points.
Or, simply put this on display in your pretty oak curio cabinet and you will definitely have a conversation piece for your attachment collection -- very strange in appearance, wouldn’t you say? It kind of looks like a preying mantis.
