Need help enlarging my pattern
#1
I have a few patterns mostly paper piecing, some regular piecing that are 5" unfinished ...4 1/2" finished. I would like to make these 12 1/2" unfinished...12" finished. I have a chart but it does not have 1/2" sizes. Can anyone tell me how much to enlarge this to make it 12 1/2" unfinished? Thanks!!

Do you need exactly 12.5? If not, you might simply take the pattern to a copy machine and enlarge about 250%

This was sent to me last week when I asked a similar question, though mine was a much simpler pattern . http://posterazor.sourceforge.net/

Work with finished block sizes, then add the 1/4" seam allowance.
(New block size) divided by (current block size) times 100 = % to enlarge
12" divided by 4.5" times 100 = 266.66666666 or 267%

Are these Dear Jane blocks?
The paper pieced ones are easier.
You can blown them up, as suggested up thread, by 260%.
If you use extra big pieces on all the positions that hit the outer edges, you will able to trim down the block to 12.5" finished, without compromising the inner design.
As for the regular pieced blocks, you want to make sure that the underlying grid layout is the same.
For instance, if you have a 4.5" FINISHED 9-patch block, then each FINISHED unit its 1.5".
In a 12" FINISHED, version, that's easily enlarged to 4" FINISHED units.
Easy to cut and piece.
You don't want to end up having to deal with cutting pieces that measure 3-7/16".
So that's why the block names would be helpful.
Of course, you could use the same method as for the pp blocks.
Enlarge them, and either oversize the outer pieces, or put a little border around to get them to size so they match the other blocks.
