So, I have learned about rib stitching and all I can say is DAMN! That is going to take some time! Yikes.

I didn't watch the video yet, but have ribstiched a few planes. It's really not that bad once you get into it. Probably 3 or 4 hrs per wing. Not the end of the world by any means. Just bite the bullet and go for it and when it's all over you will say. I guess it wasn't that bad after all. JImChuk
You can make it slightly more challenging by not considering where exactly every pair of top and bottom holes lay in relation to the spars and sometimes even the braces inside the wing. Simply having two holes placed such that you don't see straight through to the other side is enough to make this more challenging. I had to fabricate bent needles to get around one spar (every rib). That means you start and stop twice on every rib. Try to avoid that. Even with my oversight I didn't mind the job. Kinda Cathartic. I read the book on stitch spacing and blindly laid them out as suggested. It could have been much worse. My holes were only about 1/4" inside the spar. All said, My spacing is equal every time and looks great.

I think I figured it out so spacing of 2 3/4" or 3" missed the spars on both sides. Something like that. Just a little bit of forethought and planning goes a long way. The second time around is usually easier because of our learning (hopefully) from our previous mistakes. Easy to make needles with some gas welding rod as well. Flatten one end and drill and slot a hole there. JImChuk
I watched a few more videos, seems to be not too bad once you get that hang of the seine knot. Simply repeat, a lot
About 6 knotts and it all becomes automatic.
As Eddie said, taking some time to begin with and laying out your knot spacing to avoid spars and braces will really pay off. I layed out a pattern on a 1" strip of fiberglass wingtip trimming in pencil, then layed this strip on top of each rib and looked at each marked hole to see if it would interfere with something underneath (spar, brace). It took about 3 tries of adjusting spacing patterns before I got every stitch on every rib to go thru without interference. When this was done, I used the marks on the fiberglass strip to transfer the pattern onto the fabric.
