Sulky Heat-Away stabilizer is a traceable, stitchable, medium weight clear film the can be used as a design template or disappearing support. It is the perfect choice when you do not want residue left on the fabric; when water is not an option for removing a stabilizer; or when tearing could damage the stitching or fabric. Use it as a topper or stabilizer on fabrics that can tolerate 260 degrees - 300 degrees (cotton setting on most irons). Not recommended for high pile fabrics as it can get trapped in loops and cause sticking. Removes easily with a dry iron;– do not use an ironing press and never press with steam. Note: Do not trace designs onto Heat-Away using a permanent-ink marker. Packaged in a re-useable clamshell storage container to keep your stabilizer fresh and usable for years. All Sulky stabilizers are acid and lead free!
