Best wool dryer ball instructions?

[1blessedmama]

For anyone who's tried (and tested!) numerous wool dryer balls, what method of making them did you find to be the best and sturdiest?

I like the wound ones (I have a tut here... http://withatangledskein.blogspot.co...yer-balls.html), because I can use up acrylic scraps, too. For looks, I really like my crochet ones, though. These are the ones I would give as gifts. http://withatangledskein.blogspot.co...wool-ball.html I wind and tie off the core just like I would with the wound balls (use wool or acrylic here, too), then sew the crochet halves together before felting.
