621 Lace White — The Essential White Invisible Thread
Bottom Line 621 Lace White is the most-used Bottom Line colour in the average longarm studio — a soft, bright white that blends invisibly across the widest range of white and light fabric quilts. As a bobbin thread it is the standard choice for any light-coloured quilt where matching the bobbin to the quilt back matters. As a top thread it enables invisible or near-invisible stitching on white and light contemporary fabric collections. A continuously stocked essential.
