How to Correctly Sew a 9 Patch
Sew together three sets of two squares, right sides together, using a leader piece to sew on and off. (you should end up with three sewn pieces)
Important tip: Don’t clip the threads between patches, and don’t press them yet.
Sew on the last block for each row. Again, don’t clip threads, and don’t press.
Match the first two rows, right sides together. Adjust the fabric pieces so that they match on the first seam line in the middle. They should “kiss” each other. As you sew the rows together, flip the seam allowance up away from you for the first square. This allows the corners to “snuggle” in together nicely. Use your stiletto and hold the fabric on that middle seam allowance. Gently pull the fabric so that the two pieces “settle” into their proper, matching spots.
Once you’ve sewn to the middle seam allowance, stop and adjust your fabric again. The second square of the row is opposite: Flip the top seam allowance down and towards you, the bottom up and away from you. Because this “feels” funny for the fabric pieces, they will likely slip a little. Hold the seams firmly, or better yet, put a pin ahead of the matched seams. Once you’ve sewn to the second seam allowance, stop and adjust your fabric again, this time matching and then holding the bottoms of the fabric.
Repeat this process with the third row of the block.
Pressing a 9-Patch
Similar to pressing a 4-patch, shown here, correctly pressing a 9-patch will give you flatter results.
I finished my 9-patch off by adding a cute Around the World sort of border. I love how it looks!
