Prewound Bobbin Magna Qlt L-Light Grey Review

Fil-Tec Magna-Quilt Prewound Bobbins Egyptian Long Staple Mercerized Cotton No. 50/2 (Tex 24). Has the look of cotton but has the strength and colorfastness of polyester. The magnetic core rotates the bobbin consistently throughout the entire bobbin which results in uniform tension to the last stitc...h. Consistent tension throughout the bobbin increases stitches per bobbin. This equates to more time quilting and fewer bobbin changes. No backlash or overspin issues. 20 L style prewound bobbins per jar. 74 yards of thread per bobbin. 50 weight. FILTEC Egyptian long-staple cotton thread on our original magnetic core bobbin. Used for sewing, quilting and embroidery.
