Fray Check 液態縫線密封劑 附布料專用塗抹器

Used this on the hem of a pair of curtains I just sewed and the clear liquid dried completely invisible, which was exactly what I needed. The fabric guide applicator made it simple to trace along the cut edge without any drips, and the seam held up fine after a machine wash.

The fine tip applicator on this bottle makes it so easy to get into tight seams without making a mess. I used it on some new linen curtains and the edges haven't frayed even after washing.

I was skeptical about the washable claim, but after laundering a quilt binding I sealed with this, the edges stayed perfectly intact with zero fraying. The little applicator tip gives you real control so you don't accidentally soak the fabric.
