ok thanks. Quilter1234

You can also cut out these pieces in paper (tape them together if you need to) and then sew them together to see if you have your calculations correct...saves on fabric this way :wink:

Quoting Sandpat: "I'll tell you who can tell you exactly what size to do...Patrice...she is the goddess of this one!! Ask her.. "

First, i must say how flattered i am by the compliment. :mrgreen:

Now, of course, i reeeeeeeeeeeeeeeeally hope i get this right! The pressure!! OY! :lol:

setting triangles for on-point quilts used to irritate, aggravate and scare the stuffin' outta me until i looked closer and figured it out. The top and side triangles are nothing more than half-square triangles. Sooooo ... to get them the right size, just add 7/8" to the finished size of the whole blocks.

1. Finished block is 6". That means they'll be 6-1/2" x 6-1/2" before you sew them together.

2. To make your setting triangles, cut squares that are 6-7/8" x 6-7/8". Cut each of these in half on the diagonal. you'll end up with half-square triangles that fit perfectly.

the width of the sashing doesn't matter one bit. as long as you base the size of your triangles on the size of the whole blocks - and DO NOT include the sashing in your calculations, it'll work out every time. ;-)

thank you sooooo much. I knew I could depend on you ladies to help me out. Quilter 1234

Thanks for the clarification on this, Patrice!
Patrice to the rescue! Yeahhhh! :lol:

The math given is incorrect, but you should probably do as amma suggested and try it out with paper before you cut cloth. Whether you use call it a 6" square or an 8" square, 6.875" is not the proper measurement for either setting triangles or corner triangles. It would give you corner triangles for an 8.5" finished square.
Just make sure you are aware that doing it Patrice's way, no matter what the correct measurement is, with HSTs as the setting triangles, you will have bias edges all the way around except for the corner triangles which are supposed to be HSTs. Setting triangles are quarter square triangles.

Here is a template for a 6 inch finished block and 2 inch finished sashing.
I worked it up in EQ for you :wink:

Oops here is the template

If your block is 6 inches across, measuring it horizontally on point this is your template for your triangles

If you cut a 6 inch block and then turned it on point, here is the template for that

amma, it is 6" finished. Is that for both the side and corner triangles. Thank you so much. I did do it on paper, Let's see how I did. quilter1234
