The 9-patch is not on point.
I also assume it's a 3" finished block alternated with a 3" finished (cut 3 1/2) white square.

The 9-patch in the border isn't on point?

Your Omigosh is gorgeous! I love the bright colors you've chosen and your piecing is perfect. Please share finished pics!

Man that is an awesome quilt I just love it I have made a many of a nine patch but none looking like that well done.Keep them coming.!!!!!!!!!!!!!!!!!!

All the quilts are great and they look like Irish chains to me.

To calculate the size of the setting triangles for the border you can go to this website http://www.ctpubblog.com/2010/08/03/...ing-triangles/
They give a fairly simple explanation.
For those who wonder why they are using 1.414, it's because that is the approximate square root of 2. The length of the diagonal of a square is the length of one of its sides multiplied by the square root of two. This is all based on the Pythagorean Theorem.

Its looks like a 9 patch with the plain color being like an x on the block and then a plain white block. The borders look like its a triangle then the 9 patch and another triangle, its put together with a 45 Degree angle I made a border with the same type of slant one time.

I would say the interior of the quilt is a 9 patch and then a solid block, alternating. The border definately looks like the 9 patch on point --you can see the seam lines go across and form a "square" block.

It's a single Irish Chain in the center section, they are not on point in the center. A single Irish Chain is a nine patch block and a plain block, alternated. this one is scrappy...and I really like the on point blocks in the border.
The attached picture shows a scrappy Irish Chain.
This is one of my favorite patterns, simple to make, and can be very striking.

I love the "Oh my gosh" quilt. Is that the name of a pattern? I would like to make that.

It is not an illusion. In her comment remarks she posted:<DD id=Blog1_cmt-6636612879916303164 class=comment-body>"I should have mentioned that for the quilt's body Mom set a tone-on-tone hour glass between the nine patches. The hour glasses were quilted in the ditch with an "X" while the nine patches were outlined around their borders. An egg-and-dart pattern was quilted in the borders."

Thanks to all the board members for the calculations & pictures.

If your quilt has blocks set on point, it will have triangular openings around the outer edges of those blocks where each diagonal row of blocks ends.


You will need two sizes of triangles to fill in the blanks. One size fills in the gaps along the top, bottom and sides of the quilt. Four smaller triangles are used to create the quilt corners.


Corner triangles are half-square triangles, created by cutting a square in half once diagonally to produce two triangles with the straight grain on their short edges.


Side setting triangles are quarter-square triangles, created by cutting a square in half twice diagonally to produce four triangles with the straight grain on their long edges.


To calculate the size of the two squares, start with the finished parent block size times 1.4142. For the corner squares, divide this by 2 and add 0.875". For the side triangles' squares, add 1-1/4" to step 1.


Unless you have experience with these setting triangles, it is recommended that you add 1/4" to 1/2"; you can trim off any excess after assembling the blocks and triangles.

if you have an iPod, iPhone, or iPad you can down load this app call QuiltRef and it give you this information. You cn also plug in you block size and it does the math for you. I would recommend making the triangles bigger and then square up the block.

The pattern is a single Irish Chain. If you look

This pattern is a single Irish Chain. Google single Irish Chain and you will find many links with free patterns.

That is so pretty...Thanks for sharing....
