Setting triangles and corner squares on 8 pointed star
 

I have read several ways to measure and cut setting triangles and set in corner squares but I can not find out how to actually sew them in. Can anyone tell please me how to do this? Is a tutorial available for this/
Thanks

I bought a special ruler as I love blocks set on point. It came with directions. I can't imagine there's not a tute on this board as that is such a common issue.

You have to do it using a set in seam more commenly known as a Y seam. There are literally hundreds of tutes and You tubes on the internet. Just google "how to sew a Y seam" and pick one.

I can't picture the 8 pointed star you mean that needs setting triangles with Y seams...... I can only think of these, for example. Are turning your block on point within the quilt, perhaps???

I think the original question refers to the star made with eight 45 -135-45-135 degree diamond shapes

My interpretation of the question meant how to sew in the setting triangles and corners on a diagonally set quilt. All you do is sew them at the ends of the diagonal rows in the correct orientation. Match the square corner of the blocks to the square corner of the setting side triangles. For the corner triangles, find the middle of the long side of each the corner triangle and the block in the corner.

OOPS, I guess I gotta read the title of the question too. You are talking about a "lemoyne star" and need look up a tute on "Set-ins". Basically, you sew one side at a time but DO NOT stitch into the seam allowance. Remove from the machine to align for the third seam of the Y-seam. Do not plan to "pivot".

I just keep learning things from this blog that are amazing! Thanks for posting this subject. It looks fairly simple. Who would have thought to even develop a block that required that sort of seam, but then people who sew do this sort of thing without even thinking about it. As my mom used to say, "Where there's a will, there's a way". lol

When people did most of the piecing by hand, a set-in piece was not a big deal.

I have never had to use a "Y" seam yet (thankfully) because I am afraid of them. They seem daunting.
