I started laying inside glass horizontal on my second canoe and did all the rest like Nick does in this video. To me, it takes away a lot of the stress. I now do the wedge at the ends first and let them set up before continuing.
Small batches of epoxy is another great tip. Keeps from getting epoxy pooled beneath the glass. I understand his point about the extra coat on the inside but I've never done it. I give a light sanding with 220 before varnish and I'm sure it isn't cutting into the cloth. After 3 coats of varnish I doubt there are any pinholes. Nothing wrong with the 2nd coat, i just dont think its necessary.

Laying the cloth, side to side, would save cloth for sure ! I have bags of cloth trimmings, left over from full length glassing ! I have thought to use it up on a hull. Maybe someday.
The over laps, add stiffness to the hull, it's just not visually as appealing, especially if you plan to market the canoe.
Small batches, and having someone, to accurately mix them is a great help.
The extra coating of epoxy, on the inside, does add to the waterproofness of the hull. I too think extra varnish would aid, in sealing the hull.
Like I said, I have intended to just go with one coat ! I just wasn't satisfied with it.
Sanding into the cloth, has been a fear of mine. That's one of the reasons I'll fill the weave.
I don't always agree with Nick on somethings, but in My view, he puts out the most informative videos on YouTube !
