What's your secret...

...for hemming the corners of cloth napkins, tableclothes, etc.?

I have a book guide, but haven't been able to master it without the corners becoming these huge bulking messes.

Please help!!:

I just saw something about this... let me see if I bookmarked it. Ah ha!
Rolled Hem Foot Tutorial

Basically comes down to rolling the first bit of the hem by hand and sewing it down, then inserting the fabric into the foot if I remember right.

I "cheat". I use the rolled hem function on my serger and call it good.

I sew from both directions almost up to the corner, then trim away as much corner fabric as I can while leaving enough to fold over and make a neat corner, pin and sew.

[rubelin]

I fold all the corners in at a 45 degree angle, trim them a bit and then double-fold the rest of the sides, meeting at the corners. It works best if you press them before sewing, which takes time, but I figure I'll be using them for a while

I would do the corners as darts (turning inside out) like a baby blanket.

Does this make sense? It might be tighter on a smaller hem, but I think it would look nice.

I do it the way art4babies mentioned.
