Finished it all today, with some small breaks. And this is why I need to get more #Embroidery floss soon. Visible mending. 馃槄
While I only needed to mend a small part I decided to do it all along the edge for future strengthening!
Oh, I also got to practice how to switch thread 2 times, and make it secure and I think I did pretty good, I made some doubles on the top but it looks quite neat.

The very edge where I switched from one thread to another, basically I slid in hidden thread, doubled one stitch and back threaded across the top the old thread to secure it. The new one binds itself in immediately. It's only double thread for 2 stitches on the top.

A quarter of the heating pad, showing of the green blanket stich all the way around the red edge of the otherwise white pad.

Closeup of where I've used a yellow tacking thread together with a fabric glue stick for attaching the edging and stitching it in place so it doesn't move around when mending. Both washes out, and this heatpad is washable

Start of mending, Green embroidery floss with blanket stitches around the edge of my heatpad, which has a red edging that needs to be repaired as some of the stitches had started to break
