Quality First, Affordability in Focus At DOUBLELIN, we source materials only from large, qualified suppliers, and each batch undergoes rigorous testing to ensure strength, fineness, evenness, and other critical quality metrics. While we invest heavily in high-quality materials, we are able to offer affordable products by manufacturing them in-house and selling directly to customers, cutting out intermediary costs.

We thoroughly test our products on machines and collect feedback from end-users before launching them, ensuring they meet the highest standards of performance and compatibility.

Thread Color, Type & Size: Select from White, Black, or colored threads in 60S/2, 40S/2, or 75D/2 options.

Sewing Combos for Convenience DOUBLELIN offers Size A, Size L, and Size M Sewing Combos, each featuring a set of prewound bobbins and coordinating top thread spools in a variety of colors.

Compatibility and Recommendations Our size A bobbins (13/16" diameter, 28/64" height) are compatible with a wide range of machines, including popular models from Brother, Babylock, Bernina, Janome, Juki, and Singer. If you're unsure about the compatibility of your machine, please feel free to check with us before making a purchase.

For Brother's newer models without bobbin tension adjustment, we recommend using our 60S/2 spun polyester bobbins, which are the equivalent of Brother's #90 thread. This helps to prevent the bobbin thread from showing on the top of the fabric.
