    enlarging a block pattern?

    I came across a cute 6" square block (finished) pattern but most of my projects are for a finished 12" square. I consider myself an experienced beginner... still learning!!! HAhaha

    Q: Can the pattern measurements simply be "doubled" to make a 12" square - finished???

    I don't want to have to experiment with fabric that I don't want to use up needlessly, trying to "make it fit" if necessary. Fabric is soooooo pricey anymore

    Thanks in advance for an answer or any hints concerning this.

    Short answer - no, you can't just "double" the measurements.

    You have to remove hte 1/4" seam allowance on all sides, then double, then add it back. For example, a 4-patch made of 4 3" squares (3.5" cut) to make a 6" block would be made from 4 6.5" blocks, not 7" blocks, to make a 12" finished square.
    If you post the block, I'm sure someone on here can help you out, if you aren't comfortable redrafting it yourself.

    What Krista said, plus it's a bit more complicated if you're dealing with angles, because the cutting size isn't always 1/4" plus finished size.

    ​I sometimes work it out on graph paper without the seam allowances. You can also cut the pattern pieces (without seam allowances) from construction paper and fit the block together.

    This is why I love my Electric Quilt software program. Once you enter any design, you can make a block at any size !!!

    I agree, use EA or ask a friend who has it to help you.
    Yes you can resize the block. You need to subtract the seam allowances. Also the resizing works on the squares and rectangles. I haven't figured out the curves or diagonals yet.
    Have fun quilting! If it isn't fun, you will miss a lot.

    You could always make 4 of the 6" finished block and put them together to make a 12" finished block

    WOW! tons of suggestions and I think I "get" kristakz's instructions... with caution about triangles from dunster...and graph paper and 4 times the 6" block... will have to digest all! incl. website.

    THANK YOU all! I knew I asked the right - smart - people!!!
