HELP !! Need MATH help with this pattern
 

I am doing charity quilts for foster kids when they go to summer camp next year. A friend loaned me this pattern. I love it but I don't understand why it seems to be more complicated as drawn. I want to avoid making all those quarter triangles. The center in the block diagram is 4.5" square cut. I want to attach half square triangles on the four sides instead and then have the pieces of the dark turquoise square and green/turquoise half square triangle as sashing and the white square as a cornerstone. I have already pulled enough fabric to make this quilt. I am ready to start cutting but I just can't figure out the math. Once I know the dimension of either the white or dark turquoise size is, the rest should just fall into place. Am I correct??? THANKS !!!

I'm sorry, but I don't understand what you're asking for. Maybe because it's late (for me) - I've been going since 4:30 am...

You've got a 9-patch w/ blocks all the same size - 4 1/2"

If you give me a few minutes I can do it in EQ7 for you...

Ask and you shall recieve! What a great place!

Thanks. PM me when you have a chance. I have EQ5 and not sure if you can send it to me. It is late for me but I just couldn't get the dimensions to work in EQ5. With my disability, I seem to have lost my math skills. That is why I stick with what I think are simple designs.

I have been up TOO since 4am but I am out here on the west coast. Going to call it a night. Didn't at all see a 9 patch but that was interesting observation. Being diable, I just wanted to avoid those quarter triangles. I see so many quarter triangles that form a simple square. I would rather just work with as many squares as possible. Take care and thanks for feedback.

Here you go - these are PDFs. You will have to mirror the sashing so the green triangles end up in the right place. The lighter blue plain squares should be 6 1/8" unfinished. Please make test blocks and sashing before cutting everything just to make sure it's right.

Hope this helps!

Quarter square triangles really are fairly easy to work with -

and I think you would be a lot happier with how the block lays after it's sewn if you use them where appropriate.

I agree. Quarter square triangles would make it look better & lay better and would be generally easier. Just my humble opinion. . . .

Quarter Square Triangles are pretty easy if you cut them bigger and trim after sewing and pressing.
Here's my favorite method.
