I get that French seams will waterproof seams. My dilemma is how to waterproof zigzag stitches around velcro. My first solution is to make the inside front yoke longer and then place the diaper on the outside of that yoke (instead of using it as a pocket for the diaper). This probably only makes sense to others making diaper covers!
Someone suggested seam sealant (like the stuff used by campers for tent seams).
Any other ideas?

I would try emailing or calling Seattle fabrics in Seattle, Wa. They deal with all types of outdoor and waterproof fabrics.

Seattle Fabrics sells an waterproof sealant that I've used for seams on a neoprene vest. You can get it from Amazon too. McNett Aquaseal
It dries pretty thick so on something like PUL and diapers I'd want to be careful to apply a very thin line of it. Also it can be tough to reopen a tube once you've used it and put the cap back on. Clean the inside of the cap and the outer part of the tube that attaches to the cap with rubbing alcohol before you close it.
I've been using my neoprene vest for a couple of months with no problems so I'd say so far it works.
Mostly Babylock: Ellegante, Crescendo, Evolution, Ovation. Plus a Sailrite LSZ-1

I never had complaints from the mamas I made covers for, and I didn't seal the seams. I have heard of people using seam seal tape.
but Seam sealant in a tube is messy and ugly when it dries.
After looking at my review, I realized when I embroider the diaper cover I make a patch out of PUL on the inside
Here's a review of a diaper and cover I made
Here's how to embroider a PUL diaper cover to make it waterproof, maybe you can do the patch with the velcro toopul patch

My grandmother taught me to sew when I was 10, and I've been sewing ever since.

My sister makes MCN (modern cloth nappies) AI2's here in Aus, and she doesn't use seam sealant at all, either on the legs or the fasteners. She uses snaps, and therefore can have up to 12 punctures in the front that might leak, but she has never had a problem. Her opinion is, if the nappy is wet enough to leak through at the snaps, its been on the child too long and needs changing anyway.

I agree with diane s that iron-on seam sealing tape is much nicer than liquid seam sealant. I purchased mine from Quest Outfitters (ugly website, great products and service; no affiliation). There's no photo of it, but it's the first item on the linked page.
That said, I don't think you get enough additional protection to make sealing the seams on diaper covers worth it. I've heard some advice to put the cover through the dryer just once after you finish it to kind of melt the thread into the seam, but the seams are not going to leak in any meaningful way.
You might experiment with sewing some scrap pieces together and then making them into a bowl to hold water and see how slowly and how little water leaks through the seam. It's pretty surprising!
2007: purchased 115+, sewed 105+
So close to parity, yet so far
Trying again in 2008
Yards purchased: 133
Yards sewn: Somewhere around 95
2009? I give up
