How to Make the Ohio Star Quilt Block

This year, for the quilt guild I am apart of, I am providing instructions for how to make a different quilt block each month. For the month of December, we learned about the classic Ohio Star Quilt Block. 

 Ohio Star Quilt Block

This is a very classic block that great for everyone to know how to do. 

For a 12 inch finished block (12.5 inch unfinished), you will need to cut the following:

White  4 of 3 1/2 inch squares

White  6 of 4 inch squares

Color  6 of 4 inch squares


Using the 4 inch squares, place a white square and a color square right sides together. Draw a line diagonally, corner to corner on the white fabric. 

Stitch a scant 1/4 inch away from the line on both sides. 

 Half Square Triangle

Cut on the line and press the seam to the dark side. 

Trim to 3 1/2 inches square.

Half Square Triangle HST

Repeat till you have 12 half square triangles. 

Arrange the half square triangles and the 3 1/2 inch white squares to match the layout of the square. 

Stitch blocks together to form rows. Press to alternating sides. Then stitch rows together and give an overall final pressing.

Check back each month for a new How-To of quilt blocks! To see the other blocks, just search my blog for Quilt Guild Block of the Month.

If you would like a PDF version of these instructions, please check out Group #2 of the How-To Block of the Month Downloads.

This is classic block that has been designed and created by many people. As I have mentioned before, these block designs come from the book 5500 Quilt Block Designs by Maggie Malone. (c) 2003 but these instructions are written by me.) 

Have fun quilting!

  • Hi Peggy! That is a blog post I have planned for January 2022, so keep your eyes open for it! If you subscribe to the newsletter, I will have it included in there in the beginning of February.
    Thanks for asking!

  • Can you post how many blocks and how many yards are needed for bed sizes. Your description on making the block is easy to understand. My 2 favorite blocks are Ohio Star and Log Cabin.

  • Hey Di!
    Thanks for asking! The photo of the block is cropped a bit. There is a 1/4 inch seam allowance around the block before the points, so you shouldn’t loose them when you sew the blocks together. Good question!

  • I think my question may seem pretty stupid,but when you join the completed blocks,don’t you lose the points? Maybe I’ve missed something?
