2-1/2". It is the way I was taught and I am at the age where. you know, you can't teach an old dog!!!!!!! Mom told me the inches for everything to use - I wrote it all down, it is all memorized - too late for me. I have found the 2-1/2" looks neater, at least to me it does. Everyone has their own way, and each way is right.
To Teri from Minne-sew-ta, what do you do when you have had enough, boots, jackets, scarves, gloves, mittens, hats and you pack them all away and have a few sweat shirts and one light=weight jacket out and refuse to take out the "other stuff"??????? You freeze!!!!! That's our state, eh? Only a few more days left and we will be in the throes of Spring!!!!! High school tournaments are over, there is still snow on the ground and doggie doo-doo is popping up all over the place. So everything is uphill from now on!!!!!!!!
Enjoy the day, bind the way you like and all will be well with the world. Edie
