The pinwheel block is one of the oldest and  most beginner-friendly quilt blocks. They are usually created by using half-square triangles (HSTs) in contrasting colors, which gives the block its distinct appearance.
The pinwheel quilt block is a perfect project for sunmer. It is not only easy to make but also has a great look in different colors and a variety of fabrics.
You may have encountered or tried some other ways to make pinwheel quilt block. This is how I make pinwheel quilt block. I prepared a tutorial for pinwheel quilt block, making it quick and easy. I, of course, made it with HSTs. While making HSTs, I used magic eight technique which provides you to make eight HSTs at a time. When you need to make so many HSTs, this way is quite practical.
The most important thing with pinwheel quilt block is getting all the points matched in the middle.

Here we go:

  • Cut two pieces of  10 x 10 " squares from two contrasting fabrics. I used white and red fabrics  here.

  • Draw diagonal lines on the wrong side of the red fabric. 

  • Place the red fabric on top of white fabric, right sides together. Sew on either side of both drawn lines with 1/4" seam allowance. 
  • Cut the squares in half vertically, horizontally and along both of the drawn lines and you get eight pieces of HSTs.

  • Press seam allowances and then trim the exess pieces. Each  HST unit measures 4.5".

  • Arrange four HSTs as shown below.
  •  Sew the HSTs together to make two rows. Press the seam allowances. Sew the rows together to make one block.
  • It's finished. Isn't it lovely?! The finished size of the pinwheel block is 8.5". The options with this quilt block varies. It is really simple and fun block to make. 
      Enjoy it!
