Bosal In-R-Form 單面黏合襯 18" x 58" 黑色

I’ve been using this for bag straps and it cuts cleanly without fraying, which makes assembly so much smoother. The single-sided fusible side pressed down evenly on the first try, and the foam is just pliable enough to shape around curves.

The fusible side grabbed evenly on the first pass with my iron, and the napped spun lace backing makes it glide under the needle without any skipped stitches. I used it to stiffen a bag bottom and it's soft enough to roll but holds its shape once pressed.

Handled a tricky curved bag flap like a dream, the foam laminate kept its shape without adding bulk. I used it for a structured clutch and it was easy to stitch through without skipping stitches.
