It felt familiar the whole time but because I'm making two quilts concurrently I thought it was just because if that. Darn.
Anyhow, here's a block we haven't made.
Print or trace the block diagram onto foundation paper, number, and cut out as in the photo.
Iron the freezer paper to the right side of the block, lining up the seam lines.
Cut the small pie shapes out of the fabric, leaving a seam allowance to turn under.
Cut a 6" x 6" square out of background fabric and place it right side up of the table. Position the block right side up on top of it. Baste through all layers to secure the pie shapes. Leave room for the seam allowance to be turned under when you applique. Clip the inside corners and curves.
Cut away the extra background fabric from the back of the block.
Applique the quarter circle corner shapes onto each of them using the applique method you prefer. Make sure to leave enough background fabric around the curved edges. I recommend at least 1" to make sure you have fabric to trim off when you're done. If this doesn't make sense just keep reading and you'll hopefully understand.
I used "freezer paper on top" applique, which is shown in the photos below.
Cut out the small curved sections from the freezer paper sections you saved earlier and iron them into place on the right side of the appliqued squares. (They may be a little wonky which is why it was a good idea to leave that 1" extra.)
Place an appliqued square right side up on the table. Lay the block right side up on top of it, using the freezer paper on both sections to line them up. (Remember that the seam allowance on the main block will extend past the actual edge of the block so you'll have to peek under there to line up the two freezer paper edges.)
Baste through all layers.
Repeat for the other three block corners.
