[Product Description] For all types of basting, including patchwork quilting basting, appliqué, gathering, pleating, cuffs, and attaching pockets. The basting thread will disappear when washed in a washing machine. Can be used for both machine and hand sewing. - Please use on fabrics that are not affected by water or steam. - We recommend testing on a fabric scrap before use to see if it dissolves. - Water-soluble sewing thread dissolves in water, so please use with dry hands. Also, store any remaining thread in an airtight bag with a desiccant. - It begins to dissolve at around 30°C (86°F) and is almost completely dissolved at 60°C (140°F). Dissolution time may vary depending on usage conditions. [Contents] 80 count, 200m Left-hand twist ■Material: 100% Vinylon This is a new, unused item, but it has been stored at home for a long time.
