It will be, eventually - the edge of a handkerchief, that is! More about that, later...much later.

What edging should I do? I dithered for
months - I'd wake up one day and decide on one, tat a sample, then decide it just wasn't what I wanted. I'd put the edging on hold and work on other projects, then I'd come back to it...still undecided.
David had put away several of my tatting books -
in a safe place - and it was extremely safe, as I had no idea where he'd put them. Neither did he! He began a search for them, and after several days, he found them and put them on the bed where he knew I'd notice them when I got home from work! The missing books included all four of my Mary Konior books!
I'm now deeply into the edging - from this book, one of my favorites, by one of my favorite designers - the one, the only - Mary Konior! If you look at the edging closely, you can see that she lifted one of the elements and used it in her "Queen of Hearts" motif (in
Tatting With Visual Patterns).

I
LOVE "Queen of Hearts" - I have it memorized and can tat it without the pattern in front of me (and frequently do!). I decided to do this edging - but almost immediately noticed a roadblock: it didn't have a corner!
Hankies have corners; sure, you can tat a couple extra elements and work them around the corner, but with an edging like this, you really need to find a way to tat a real corner. I used the mirror technique: I held a pocket mirror at a 45 degree angle and slid it over the picture of the edging until I saw exactly what I wanted to see - a corner!

Someone, somewhere might want to tat this edging - with a corner - so here is how I did mine:
following the pattern, start the Ring B at the spot where you want to turn the corner. Tat the chains and Rings C and D, then repeat the last chain and Ring D again. Continue with the pattern. You'll have two free picots in the corner element, as opposed to four free picots in each of the side elements.
