I'm in the prosses of making a D9P But I want to put it on point. I never did a D9P Or point for that matter. How do you know what sizeto make the tringles to make the quilt square? I'm winging this I dont have a pattern. Here I go again jumping both feet into the fire. Help

to make two triangles, cut a square that's the finished size of your blocks plus 7/8". cut that square in half on the diagonal.

or, to be safe, cut a square that's a whole inch larger than the finished blocks and then trim it all to square after assembly.

Would love to see a pic when you are done!

For the triangles that go on the edges of the quilt

Measure your finished D9P block (9")
Add 1 1/4" to that measurement and cut squares (10 1/4")
Cut those in quarters diagonally

You will get four triangles from every 10 1/4" square, so you can figure out how many squares you will need.

If you want a little extra "fudge" space, just cut your squares a little bigger (perhaps 11").

For the four outer corners, add 7/8" to the finished size and cut 9 7/8" squares. Cut those in half diagonally. You will need two squares for that. Again, you can cut the squares a little bigger if you like.

The reason you need to do it this way is that you want the outside edges of your quilt to be on the straight of the grain. It avoids the wavy edges, so the quilt will lay flatter.

Yes, please share with us, as you make progress on your D9P quilt. :D
