I confess I'm not a soaker.
As a kid, I soaked, but when I returned to the hobby as an adult, I decided to collect mostly mint stamps, so I've only soaked a few stamps since then. And as I posted here before, they turned out "wavy" and disappointing. That post prompted a lively discussion from several of our experts, including the recipe for Rod's sandwich bag sandwich method.
So, drawing on the things I learned, I've documented my latest attempt for your amusement:
1. First, eat a good breakfast.

You don't have to actually eat 4 pounds of cereal, but you will need a few pieces of cardboard and cereal boxes were recommended.
2. I'm using two pans. While I'm retrieving and processing the front pan, the back one is just soaking.

3. After they float, I place them on a dish towel, as recommended by Rod.

However,
I goofed by placing them face UP; don't make the same mistake. When I removed them from the towel, a few of them didn't want to release. So be sure you place them face DOWN unless you want to soak them twice.
4. After they dry on the towel, it's time to make the sandwich. I used a book as a base, then a piece of cardboard. I remembered to place the stamps face DOWN on the cardboard then covered with a sheet of wax paper (substitute for Rod's ziploc storage bags).

Not shown, I placed another piece of cardboard on top and repeated the process. Then another, ...
5. After I had all the stamps placed, separated by wax paper, and stacked, I put them in the bay window with a few books books and my "in-box" of stamp catalogs and publications.

So much for my spotless clean window.
Thanks Rod and everyone for the advice -- I'll let you know the results.
Also, if you look closely, you'll notice these stamps are all Machins. I got a great "starter" packet from McGees_org and I've been wanting to get started on them.
In 3 hours, I processed about 250 stamps.
