Featherweight Thread, PREMIUM MACHINE PIECING SET with Prewound Bobbins
Your Path to Perfect Stitches
Who hasn't savored that exquisite delight when a seam comes together just so and the thread disappears into the fabric! That's the joy of precision piecing—and on a Singer Featherweight, it's a joy your machine was born to deliver. All she needs is the right thread.
The Premium Machine Piecing Set pairs a 750-yard spool of Wonderfil's Efina™ ultra-fine 60wt 2-ply Giza cotton with 10 matching prewound bobbins, engineered specifically for your Singer Featherweight 221, 222, and Singer 301. Drop in a bobbin and sew—the tension is flawless and consistent throughout, and the spool and bobbins are wound to run out at the same time, so your sewing is interrupted as little as possible.
