The Brandywine Valley Quilters came through, as did all of you! Thanks for the help!

I know this block by the name MARYS' TRIANGLE. Here's a link for the math:

Also, from Sally Schneider - the Queen of Marys' Triangles, has this information:

Also known as Shaded Four Patch.

Hope it helps!

Could you share the finished block size you are aiming for?

I was looking for overall directions so that I could use any block size...I hadn't really settled on a size yet, although 8" finished would probably be fine.

I saved this, but haven't tried it.

I have made this block but did it as a paper pieced one. The square in the corner is #1, either triangle beside the square is #2 and the other is #3. The large triangle is #4.

You can make it pretty easy that way any size you draft it to be. Once you have it together, you can always take it back apart and use that for measurements if you wanted to, but I think the paper piece method is easy and gives you nice sharp points.

I think Eleanor Burns has a book on this. Or is one of the blocks in one of her sampler books.......Bird's Nest or something like that. It is a basic pieced block...squares and HST. My suggestion on determining size would be. Even numbered, no fractions on the Finishd block size will help you figure out the math of the components.....

The block can't be trimmed to size without loosing points. It must be initially cut and sewed accurately meaning scant quarter seams.. Draw the size you want on graft paper and measure each section with seam allowances. Otherwise a lot of speculation and figuring different sizes. You don't say what size you want the finished block to be.you say that you will determine later what size block you want it to be.

This site shows how to make the block without cutting triangles. Very good directions.

This site has even better directions, and shows how to cut the finished square to size keeping all your points.

I have a template for this block called the magic triangle by Sally Schneider Quilts. I have also found the directions for making it online. There is a book on the block also by the same teacher. I always had a problem with the 2 little triangles, not stretching them and making things go smoothly. You can certainly make this block without the template. The template is only used for squaring up the block.Here is a small demo of the idea.

and here is a version made without the template.

And last a calculator to make the size that you want.

I used all of this information and my blocks came out perfect. I made the 6 inch blocks but the same concept would work on smaller ones.
