9 1/2 " paper pieced log cabin block.
 

I have a pattern that has 9 1/2"squared up finished log cabin blocks, but I would like to do them in a paper pieced method. Does anyone know where I can download a paper pieced block this size? Thanks.

The problem with a 9-1/2" size would be that it is wider than the 8-1/2" of letter or legal paper.
With those papers, it would have to print on two pages, and then you would need to tape it together.
It would be better to print on ledger paper, 11x17".

For your PP pattern, this might be a good place to start .... Google often delivers!

Also, with it being a log cabin, it would be simple enough to draw out on graph paper.
Plus, that way, you could easily choose how wide you want your strips to be.
Then photocopy away .... again, best on 11x17" paper

great advise.....who has 11x17 paper lying around?????

Most of us don't!
.... though many have access to it through their place of work, at a printer or their local office supply store (eg. Staples), etc.

That seems like a very odd size for a finished block. I usually make 9" finished blocks. Each log is 1.5" unfinished, 1" finished.

Is there a reason why you want to paper piece this block? I've found that Judy Martin's methods for log cabins result in blocks that don't go wonky. Basically, the instructions are to cut so that log goes down the length of the fabric if possible (less stretch), use starch to avoid stretching, and (most important of all) cut all the logs to size before sewing, so that you know right away if your seam allowance is not right.

Our two local public libraries provide copiers that will use either size paper. Probably big box office stores, also.

I have a book my cousin gave me before she passed away -- it's just full of paper-pieced log cabin blocks -- I can't locate the book right this minute, but I'll keep an eye out for the book, and send you a pm.

You could also take any PP pattern of any size and have it enlarged or reduced to the size you specifically want it to be.

Maybe she wants a 9 inch finished and wants the 9.5 piece of paper to include the seam allowances?

What about using butcher paper? It should be large enough. My friend uses freezer paper, 1 copy only as she doesn't sew on the paper but folds it at the sew line and stitches down. She likes that method. Myself I can't sew a straight line so I sew on the paper and tear off. She doesn't have to tear any paper off with her method.
