This is my first written tutorial. Forgive my mistakes and lengthy tutorial. I wrote it basically for the quilter that has not paper pieced before. Hope you all can understand it. :)
Tools that are HELPFUL to have:
Carol Doak's Foundation Paper
Place your fabric front side up on #1. You'll be sewing on the lines and placing fabric on the non-printed side.
You'll be sewing on the line between #1 and #2. I take my length stitch down to 1.8. This makes it easier to take the paper off at the end.
Dry Iron the #2 fabric over. Turn it over and use the cardboard and fold over on the line between #1 and #3.
Now you'll want to use the add-a-quarter ruler and cut after 1/4".
Now you'll sew the line between #1/#2 and #4.
So you keep doing these steps until the end. Once you sew the line, iron, fold the next line, add the 1/4", sew again.
Here is how it will look like before trimming down.
When you trim, don't trim away the last 1/4" line. That will be the 1/4" seem allowance when you sew them all together. I take the paper off before sewing the star points to each other. Sew A & B together matching seems.
Now sew all 4 squares together.
Note: Once I sewed my first square block, I realized that when sewing, I should have sewed the line thru the 1/4" on the template.
