[I go by my husband, he's 6'4" and if it completely covers him up and it's wider than his arm-span, that's the size I usually finish at.[/quote]
Hahahahaa, I thought I was the only one who used a tall person as a size guide!
I'm tall and I hate cold feet, so I tend to make 'longer' quilts. Most are either a generous twin or queen size.
Now, having said that, right now I have a monster King size on the frame that I'm going to add the borders to after the center is done! (it didn't fit on the frame if I added them first)
