i also used 2" cut strips.
the best thing about a log cabin quilt,are the many different layouts!

There is no set size, it will depend on what the pattern and block size you want is. And the sizes of the LC strips don't have to be the same. Check out Barnbum's Floral Log Cabin. The two sides are different size strips.

It depends on the size of the quilt or pattern. The one I'm doing now states 1 1/2" strips, the one in my avatar is 2" strips, and others I have done are 2 1/2" strips. I don't know if it's a personal preference or just the patterns, I myself, like the 1 1/2" strips, but, they are alot more time consuming.

I have one going now and its a 1 1/2, no matter what size you do... make sure you have a perfect 1/4 inch seeam allowance, other wise it is going to make you fustrated. I originaly started with 1" and got fustrated and put it away and started the 1 1/2".

Personal preferences!

When I was looking for a Log Cabin pattern, most called for 1 1/2" strips. However, I used 2 1/2" strips, as I prefer that size. So, I agree, it's personal preference. And, remember, it's your quilt, right?

I like the variation of widths too, especially for a scrapy quilt. That way if you have a 1 1/2" strip you can use it. have fun!!

I made one from a Jelly Roll = 2 1/2 inch strips.

personal choice. but the 'norm' is about 1"- 1 1/2"---finishing at either 1/2" or 1"---just depends on the look you like, how wide you want your logs to finish, how big you want the block to be- how many 'rounds' you want to put around each block.
i find log cabin blocks to be horribly tedious- so for me the larger the strips the faster it is going to be over with. that being said- it seems (unless it's a really big-king sized quilt) that you loose the 'look' if the logs are more than about 2".
those of us who make scrappy quilts do not worry about consistant size strips- i prefer log cabin blocks that have variable widths in the logs ranging from 1/2" up to about 2" in one block.

I've seen antique quilts pieced with one inch strips too. A gazillion strips! Very graphic.

I agree that it sort of depends on the size of the quilt. A small baby quilt or wall hanging would have very few blocks if made with 2 1/2' strips, so you'd get less repeats, and it wouldn't be as graphically pleasing.

But different strokes for different folks. The only person who needs to be pleased with your quilt is YOU!
