Looking for advice. I've always used the "around the thumb & elbow" method, then wrap each end around the middle a couple time & plug them into each other. That makes 'em look perdy hangin' on the garage wall, but when I go to use one, it always ends up in a tangled mess. Who's got a fantastic system for extension cord storage they don't mind sharing?

Your technique is ok. The problem is the extension cord itself. Cheaper extension cables tend to bend, twist and tangle because either it has fewer but larger strands or the insulation being made out of poorly pliable material. Or a combination of both.
Do yourself a favor and make your own extension cable out of SJOW or SOOW wire cable. Not cheap but it should be the last extension cable you'll ever buy. Water proof, great resistance to most chemicals and uv light. The best part is it doesn't tangle, kink etc. The sjow are rated for 300v while the soow 600v. The sjow are suitable for most of a homeowner's needs. The soow just handle higher voltage and also has a very thick insulation. Both uses a rubberized insulation that has very high tolerance for heat or flame. If not on sale, expect to pay $10-15 for the male plug and $15-20 for the female end.

Those are some of my shorter 12 gauge extension cables. Also have some longer ones that are 10 gauge.

The thicker wires are the soow. All 12 gauge.
Thanks Jules! Looks like I've got another summer project.

I use one of those reels for my 100' cord. It doesn't tangle. However, Jules' solution looks more fun.

Currently good prices on the leviton plugs. I only use either leviton or hubbell end plugs. Roughly same quality but the leviton are a bit cheaper and tend to go on sale on Amazon, sometimes up to 75% off especially the colored versions.
Some samples below.

Chain braiding (and/or daisy chain) works well too. Hard to explain without a visual but easy to find .
+1 all mine are braided
Something else I picked up from my Dad.

@Jed.cook Here is a video (somewhat crude) that shows a typical braid used a lot by electricians:
