I have a full enclosure on the boat now that is worn at all of the zippers, and the seams of the zippers are starting to split. The fabric is worn, but not torn and I think I could get another year out of it. If it is just the zippers that need to be sewn, will a household machine work, or should I pay the local shop about $250 to sew them for me? I?m not planning on attempting to remake the enclosure on my own, so I don't think paying >$600 for the proper machine makes sense. But that would allow me to attempt to reupholster the seats in a few years.
