Question

The sleeves on the website doesn't work, there is no way to seal the other end.

Answer 1

Hello,

you seal the other end the same way you sealed the previous one. It may sound silly but it is useful to use simple hair straightener, it has two evenly heated surfaces, which make sleeve parts to stick reliably.

Open shell and set accurately on the stitches surface +- 1mm this stuff without any gap and close shell.
