Update: I managed to fix this blanket as best as possible given the situation. No more big holes and the customer now has 2 blankets instead of one 3m long one. I just wish I had have been able to tackle the restoration with wool and needles rather than a sewing machine.

Need urgent advice from experienced knitters
Hi everyone, been awol due to work and other commitments but I am stuck at work and have been asked to restore an old knitted blanket where the wool used to join the pieces together has perished. I would prefer to restore this blanket properly by hand using wool but do not have the luxury due to customer request and lack of time and supplies where I am. Also the other problem is I only have access to a sewing machine and overlocker at my disposal and needs to be done today.

I have fixed up some of the holes but now the customer wants it cut in half. I have found a place where i can undo the whip stitching except it has a band knitted to the edges. Any suggestions as to how I would handle the band after cutting so it doesnt unravel? It is a ribbed band. I have added a pic of the band area. Thanks for any suggestions
