Anyone?

Evening All, I know that others have had the same issue I have with regards to button holes coming loose and wondered what they had done to fix it. I intend to resew the edges myself and perhaps add an extra layer of material on the inside to reinforce when I hem the bottoms which should do the job but wondered what else had been done. I know in the past the jeans of been, very kindly, either replaced or repaired by IH but I bought these 2nd hand and am willing to effect the repairs myself. Cheers all
