I would like to make this 8 inch block into a 12 inch block. Can anyone help me with how to enlarge this pattern. It's from

http://www.quilterscache.com/S/SickleVariationBlock.html

I could increase it by 25% but wouldn't that would also include increasing the seam by 25%.

I've think I figured part of it out. The 2 1/2 x 10 changes to 3 1/2 x 14
The 1 1/2 x 12 changes to 2 x 16
Am I right?
But how do I change a 4 7/8 square? Would it become a 6 7/8 sq?

hang in there Debbie, I can hear Patrice's brain clicking away. LOL

I've been trying to do the math and made some editing on my original post please reread it and tell me if I'm right or wrong.
Patrice I can hear you thinking, click click click.

i can't do it for a few hours yet. i took some so-called non-drowsy cold medicine. got me so stoned somebody else had to drive me home.

as soon as i sober up, i'll check it out.

whooohooo!!!!
:mrgreen: :shock:

Debbie, that block is so pretty! Each of the sections (4-patch and half-triangle) work out to be 4" squares. You want them to be 6" squares, to add together to make a 12" block. Make your squares 6 and a half inches, to include the quarter-inch seams ... :wink:

OH MY GOD!!!!!!! I can hear everybody brain clicking away. Time to get out those old high school math books and dust them off.

Debbie,
You're right about the seams. I just spent time reducing a block. Subtract the seam allowance first. Adjust the size of the finished piece and then add the seam allowance back in.

I would guess the HST would be cut at 6 7/8". The squares at 3 1/2". The four patch squares at 2".

No guarantees. I've only had a half cup of coffee and it's only 8AM here. :lol:

oh, good. i'm glad somebody came to the rescue. now i can go back to sleep.
:D

I thought that was it but I wanted someone else to tell me it was right before I started to cut. Thanks. And Patrice get off the computer and go to bed, right now. Mama has spoken.

Do a test run first! Don't cut into your good fabric until you're sure!

Don't ask how I know this! :shock: oops!

Patrice, you may as well go sleep it off! You'll feel better in the long run!
Take care now! Listen to Debbie!
