I purchased a precut log cabin table runner from Jordan fabrics (love it by the way) and measured the width of the strips. They cut theirs 1 7/8 inches.....I'd round up to 2 inches myself.

Many folks use 2 1/2" strips because of precuts and because it is an easy size to use. BUT - you can use whatever size you want. I have seen some great looking quilts that have giant logs and some made up of very tiny logs. What are you most comfortable with? If you like to do a quilting scroll in each log, then perhaps a 3" or 3 1/2" cut strip would be better. What is your stash full of? If smaller bits, then use a narrower strip. If you use the 'darker' side as a 2 1/2" and the lighter side as 1 1/2" strips, you will get the curved log cabins. Always remember - IT IS YOUR QUILT and YOU get to make the decisions.

Back in the 80s, we made a log cabin for dh SIL, husband cut, I pressed and his sister visiting us sewed on the machine. With E. Burns pattern, we completed the top in one day. Second day, we tied it with DMC floss so the SIL could get it hand quilted by Amish in the community. No, we did not get a picture back for our records, so I cannot share a picture of it. We spent $75.00 on fabric for it, King size, back then.

I really love 2 inch strips. Not too fiddly but not really tiny either.
