Foot Ovens," I figured I had stumbled onto the perfect solution.
If you look closely at the heel, you can see that I didn't get my wraps and turns closed as well as I should have, but this was my first sock that utilizes a wrap-and-turn heel. The second one has no visible "holes" at the heel.
One other thing I learned from my first toe-up sock: Use a super-stretchy bind-off for the top. I didn't for my first one, and I can just barely get it on and off. I used this bind-off on the second one, and it slides on and off perfectly.
One last note: I tend to wear socks around the house instead of slippers, so I painted puffy paint circles onto the bottom of each sock as a non-slip measure. It works great, but don't try it on socks you're going to wear with shoes. I tried them with my boots once, and they didn't want to come out of the boots. :)
