I gather that when writing the Torah, there is a maximum allowable space between columns.
Hence, my question, which may be based on the above assumption...
If the stitched seam between two parchment sheets is beginning to fray such that the two sheets are beginning to separate, is there a maximum spacing or length of breakage allowable before the Torah would be considered pasul?
If there is a maximum allowable spacing between columns, would it become pasul if any part of the gap exceeds this spacing? For example, part of the seam is ripped but not its entire column length. If even one line between two columns is too far, is that a problem? The majority of the seem needs to be ripped? Or, how much? Or is it good as long as there is even a tiny piece still sewn together?
