    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!!

    I have dial up internet and it takes about 25 minutes to post one picture, so I never get to post pictures, sorry.

    Lord, I know about the dial up. UGH! Do you know the block name? Got any idea where we could see it?

    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.

    I ALSO have dial up. You just need to change the size to no bigger than 9" on the longest side. Someone on the board may know where there is something for you to use. I have Photo Deluxe 4.0 which allows me to scan, prep the picture for e-mail and change the size. I had to download 7 pictures to PatriceJ each in a separate email with each taking about 2 minutes. Nice to know I am NOT the only person on a budget !!! MTS has the right answer so GOOD LUCK with your project!! :lol:
