A friend of mine had a tablet woven belt which was partially eaten by her cat, and this band has a lot of meaning for her, so I offered to repair it. I've done this a few times before, though this is more extreme than some of the others. However, the pattern was simple, and I was provided with the original material. Unfortunately, I rushed a bit, and made a few mistakes, so the repair is not as clean as I would have preferred.
I decided to tackle the big chunk out of the side first, as it was the largest, as well as being the most complicated since the threads would need to be rewoven into the band at both sides of the gap.
As I placed enough strings, I threaded them onto cards. On this part, I screwed up when placing the initial threads, because I should have placed half on the front of the band, and half on the back of the band, but I placed all of the threads on the front. This meant that I had to unpick and draw the original weave into the band, or it would just hang out the back of the band.
The purple dots in the middle of the band are places that I did not pull taut before trimming, so I fixed them by pulling them tight using tweezers, then re-trimming.
Once I finished reweaving the damaged part, I used a needle to run the thread ends into the weft channels to anchor them.
I used pins to hold the thread bits from the original weaving where I wanted them, so the replacement strings would pin them in place, since they were not long enough to draw into the weft with a needle.
A little wonky in places, but functional.
The remaining damage.
On this part the damage was minimal, so I just used a needle and thread to replace the broken parts, anchoring my thread ends through the weft to "tie" them off.
The last repair was at the end of the band, and the damage was extensive, but the threads from the replacement weave would not require being drawn back into the band.
I added new threads in the same way that I did before, and threaded them onto cards.
Attached the band to the loom, and added some extra strings to hold up the rest of the band.
I should have added more threads to hold the rest of the band in place, and pulled them tighter, because the thread ends from the original belt obscured that the band was slightly twisted, not flush with the replacement section. That would have made this a much cleaner repair, and it would not have been as squirrelly to weave.
