Let's learn how to sew a Birds in the Air quilt block! This easy block is used in making lots of other blocks. Hmm, if you put it on point, it could be called Fish in the Sea!
I can't believe I forgot to take a picture of the fabric pieces needed to make this block, but they are pretty easy.
Light: 1 - 3" square; 2 - 2.5" squares
Medium/Dark 1 (Green): 1 - 3" square
Medium/Dark 2 (Red): 1 - 4.5" square
Half-Square Triangle (HST) Unit:
Cut the 3" Light square and the 3" Medium/Dark 1 square diagonally in half from corner to corner. Pair up one of the Light triangles and one of the Medium/Dark 1 triangles and sew together on the bias cut edge (longest edge).
I find it VERY helpful to spray starch the bias edge of pieces to make the pieces more stable and help prevent stretching.
Square up the HST to 2.5" square.
I usually made HSTs using a different method - you can find that tutorial here: https://fabric406.com/how-to-sew-a-basic-half-square-triangle-block/
Now you can sew a 2.5" Light square to one of the Dark/Medium 1 sides of the HST you just made. Press the seam allowance toward the Light 2.5" square.
Next you sew the other 2.5" Light square to the other Dark/Medium 1 side of the HST. Press the seam allowance toward the Light 2.5" square. Interesting looking little unit!
Completing the Block
Take the 4.5" Medium/Dark 2 square and mark a diagonal line on the back from corner to corner as shown below.
Lay the 4.5" Medium/Dark 2 square on top of the L-shaped unit and sew on the marked line. I prefer to sew right next to the marked line as you can see in the picture below. This method takes into account the thickness of the fabric and thread when opening up the block.
Fold the 4.5" Medium/Dark 2 square along the stitching line. Line up the corners and press.
Here's what the back of this step looks like.
Unfold the 4.5" Medium/Dark 2 patch and trim away the excess seam allowance.
Open the block back up and there you have it! A Birds in the Air block! Trim/square up the block to 4.5" square if needed.
I hope you have enjoyed this block.
