Measurements for 10 inch log cabin block
 
Where can I find measurements for 10 inch finished log cabin block using 2 inch strips? I have searched for weeks. Mostly what I find is using a 2-1/2 inch strips. Any help on resources? Thanks.

Hi, You won't find one because the math doesn't work. A 2" strip finishes at 1.5". 1.5 does not divide evenly into 10". a 2.5" strip finishes at 2", and, as they say "2 goezinto 10 an even 5 times".

Will it need to be paper pieced?

Will it need to be paper pieced? Jordan Fabrics sells log cabin block kits that finish out at 10-1/8th inches. Their logs appear to be 1-1/2 inches finished, which would be 2 inches unfinished. Their blocks look perfectly sized for a table runner or table topper. Any thoughts? Thanks.

The Log Cabin kits from Jordan Fabrics aren't paper pieced. One kit makes 12 blocks, but if you want a bigger project just buy two or three kits. I don't think it would be noticeable if you trimmed the block down to 10".

OK, a bit of clarification needed. When a block is 'finished' it usually means all sewn into the quilt. Some folks refer to a finished block size as when the block is completed, before it's joined into the quilt. Which are you referring to?
The log cabin kit that you talk about to actually finishes at 9 5/8". The unfinished block is 10 1/8

There are 7 equal patches across the 9 5/8" finished block. So each strip finishes at 1.375" (9 5/8" divided by 7). If you add the seam allowance back on, each strip would start at 1.875". Something that's probably causing a bit of confusion with this specific kit is that it's flannel. I'm guessing that you are correct in that the strips start out at 2", but flannel takes up more room in the seam. If you used quilting cotton, and started out with 2" strips and maintained your quarter inch seam, and had the same number of rounds as the Jordan example, you would end up with a block that measures 11" before you sew it into the quilt, and 10.5" when joined.
I guess what are you trying to do? Specifically use 2" strips? end up with a 10" block (after sewn into the quilt)? or a 10" block before you sew it in?
There would be different solutions depending on your goal!

The aauquilt Go big die cuts strips at 1 1/2 width finished size 12.5 inches but you could leave off last two rows

You can adjust the size of the center square, I think, to use 2" strips and end up with a finished block size of 12". I might try to do this in EQ7 later on to see what happens.

I have never needed to paper piece log cabin blocks, and they come out fine. It helps if you starch your fabrics before cutting and square up regularly. Some people will make the last round wider so that the block can be squared up at exactly 10.5" each; typically any small variations in that last round will not be noticeable.

Edit: I tried jotting down on a little notepad, and have had only one cup of coffee so far, so don't trust my judgment. However, looks to me as if 3 rounds around a center square will be 4.5" per side (3 rounds at 1.5" each), so 9" total finished, or 9.5" total unfinished. If you add a 1" finished square to the center, that makes a block of 10.5" unfinished, which will finish at 10". This means you can use 2" cut strips for the rounds with a 1.5" cut center square.

I was not looking at the flannel log cabin blocks but just the cotton fabric ones. You are right - I did not read the explanation thoroughly. It is 10 1/8 inches unfinished and 9 5/8 inches finished. Still, if you start with a 2 inch center block (2 1/2 raw edge) and make 7 rounds, what size would the finished block be? I'm not too great at math since I had a head injury in an auto accident many years ago. I surely do not want to go about cutting each piece as I went along - too time consuming. I am really trying to find out how long each log would need to be for cutting. Thanks for your help, Rosalie

I think I can work the measurements out for you. Just have to find some graph paper (and double check my results before posting).
