Sulky Solvy is like magic! It is the perfect temporary stabilizer that is a see-through transfer agent and will dissolve in water that is 33 degrees to 200 degrees. Use as a design template, as a pattern guide and a stitch support. Ideal when you do not want any stabilizer to show on top or bottom. Use as a topper on napped fabrics like towels to keep the loops or piles from poking through; also to prevent stitches from getting lost in any fabric and to enhance the clarity of fine lettering and detail stitching. All Sulky stabilizers are acid and lead free!
