Sue-Even us Newbies wanted to do something special for someone who is really special!!
ME has the wonderful attitude, you get to create it yourself. The technical rule is 'centered both ways on the cuff.' But the real rule is, do what your creative heart tells you to do.
I am partial to the cuff centering because I would not care to have an imprint of a monogram on my forehead in the morning. Since I don't sleep on the cuff, that works for me.
I just could not help but look on the Net for something special. These pillowcases, as shown, costs $110.00 for the pair, standard size, (King is extra). For that price, I hope they bring coffee and the morning paper!

These are so beautiful, they take my breath away. I am going to be doing a blog this week (watch for it on Friday, July 18, 2008) on 'endless hooping' which is what this photo depicts. Photo courtesy of Horchow, Fashion Bedding.
Do the monogram for your special friend, and save the endless hooping design for yourself, you deserve to be pampered.
