Unfortunately this is a permanent adhesive. Even though it says repositionable I believe that means while you are using it. Once cured and dried it will not wash away like normal spray basting adhesives. The "safe for fabrics" is more for making repairs to upholstery in areas that won't be seen or washed. Here is a link to the technical data sheet that contains an 800 number and email you can try contacting them but I am afraid there is nothing that can be done at this stage to salvage the quilt. https://dm.henkel-dam.com/is/content/henkel/TDS-2235316-US-Loctite-General-Performance-100-Spray-Adhesive-Spray-Can-13.5-oz-2017-11-30pdf
