Steam a seam fusible web - 1 metre
Steam a seam is a heavy duty, iron on, fusible web that is used when you want a permanent stick!
It is very tacky which makes it ideal for fabric collage and mending and patches.
It can be quite gummy to sew through on machine or by hand, so for applique that requires a lot of stitching though, vlisofix might be more suited for you.
This comes 24" wide on the roll.
