Hey Tmiddled,
I tore a 2 inch cut in my LE and I did not want to get the LE seem unstitched as I feel that would weaken the LE much worse so I did like Kitehard recommended but with a twist.
1. Hand stitched the cut so the dacron would not separate (could have stepped this step, made it a bit raised on the finished product)
2. Remove the bladder and basically reached inside and pulled the cut part out the zipped hole (don't over stress the material as it tends to breakdown the sealant impregnated in the dacron - I suppose on the cheaper kites, material looks diff on the REV)
3. Stuck a piece of adhesive dacron (from kitefix) on the inside, pushed the material in the through the zipped hole.
4. Cut a patch and stuck it on the outside, marked out a grid with a pencil and stitched a zigged zagged pattern. Pushed tip of needle through first point and line up tip to come out second point and threaded nylon through (just make sure you are not stitching the other side of the LE). Did this around whole patch twice so the second lap completed the zig zag. Used Kitefix glue and smeared it over the patch for a better abrasion protection.
Made a couple of mistakes by not working out the start and finish points and playing around with different stitches.
Cheers
Rich
