While looking and reading the posts of quilts and designs, I am simply amazed at those of you who can 'rescale' the sizing of a pattern. Maybe I should have paid more attention to math in school. How is this done? :?:

it's actually pretty easy when broken down into component parts. Take the block you want to enlarge, and figure by how much. If you want to double it, take each piece, remove the seam allowance, resize it to twice the size (say, from 2" to 4") then re-add the 1/4 inch seam allowance all around. Or you can simply photocopy it at 200% then add the seam allowance. And I always said, if they had taught me math through quilting, it would have been a snap--geometry, algebra and trig all are useful quilting knowledge!
I use tissue paper, cut the size of the finished block, for 9 patch block fold in 1/3s then fold the other way in 1/3s, then draw any lines you need, like half sq tris then trace to macke templets on freezer paper, and add 1/4 inch seams.
That went right over my head. LOL. I will have to read this again later. I think there is a tutorial somewhere you can print it out. Maybe ask Craftybear too, she rocks at finding these wondeful things for us. ♥♥
I've been working through Quilter's Academy Volume 1 and they lay out how to calculate fabric needs and along the way I picked up how to recalculate at least for simple blocks. I haven't tried to re-size a complex block yet.
Basically break it down into component parts and also figure out what your basic block grid is - is it 3x3; 4x4; 5x5 - as this will make a difference in how large a block ends up.
The Celestial Circles quilt on my blog is enlarged to accommodate the suns. Ideally, it would have been a half inch smaller for each block to trim a little closer into the suns, but that put me at a number not divisible easily by 3 which is the basis for the grid.

I agree with the geometry and trig part, but NOT algebra. Let's just say this wasn't my favorite subject in school.Quote:

This is really good information. I must print the chart and use it. Also, I did not know about not including the seam before resizing. Your help has been very beneficial. Thanks.
