My S2000 soft top got vandalized some time ago. Evidently I solved the problem using that old grandma's technique: some line and a needle.
But another problem happened. The spot where the fabric was teared was near a chronically tearing location. My patch increased the fabric tension and so another tear came up later.

2nd - Cut the patch on the outside and iron-it down.
Recommendation: to avoid stress on both the motors and the fabric, I recommend wrapping the lower with bar in plastic fiber computer cable guides, like I've done here:
