This quilt block tutorial is for the 9-inch and 12-inch size of the River Scraps quilt block. When I shared the River Scraps baby quilt tutorial, it was made with 15-inch blocks and I received requests for smaller blocks.
You will find several techniques for cutting your half-square triangle blocks. Enjoy this easy, classic quilt block tutorial and download the worksheets for blocks.
9-inch or 12-inch block
Cutting the fabric
There is no yardage as scraps were used for the blocks.
9-inch quilt block:
- 16 – 2” squares assorted prints
- 4 – 2 ⅜″ cream squares (for half-square triangles)
- 4 – 2 ⅜″ square assorted prints (for half-square triangles)
- 12 – 2” cream squares
AccuQuilt dies you can use:
The 6-inch GO! Qube Mix & Match set can be used to make the 9-inch block.
12-inch quilt block:
- 16 – 2½” squares assorted prints
- 4 – 2 ⅞″ cream squares (for half-square triangles)
- 4 – 2 ⅞″ square assorted prints (for half-square triangles)
- 12 – 2½” cream squares
AccuQuilt dies you can use:
The 8-inch GO! Qube Mix & Match set can be used to make the 12-inch block.
Sew with a ¼” seam allowance and press to the dark fabric or press your seams open – your choice.
Each block starts out as a 16 patch block with 4 rows of 4 blocks.
AccuQuilt die for easy cutting
My half-square triangles for the 9-inch block were cut using the AccuQuilt GO! 2″ finished Half Square Triangle die. This same die is included in the GO! Qube Mix & Match 6″ Block set.
My half-square triangles for the 12-inch block were cut using the AccuQuilt GO! 2½” finished Half Square Triangle die. This same die is included in the GO! Qube Mix & Match 8″ Block set.
Use the following diagram to sew the block together.
If I am cutting by hand, I prefer to cut my squares a little larger and then trim to the perfect size of half-square triangle.
Easy Angle Ruler
You could also use the EZ Quilting Angle ruler to make your half-square triangles. Before I had my AccuQuilt GO! cutter, that is what I used all the time. If you buy it, take a look at the Companion Angle ruler as the rulers work together to make flying geese blocks in multiple sizes and other quilt blocks.
I had someone email me asking if they could use their 2½-inch strips to make this block. I pulled out one of the first rulers I ever used for half-square triangles called the EZ Angle ruler. It works great, you can cut the 2½-inch squares and also make the 2½-inch half square triangles from jelly roll strips.
If you only have 2½-inch strips of fabric, you can use the EZ Angle ruler to cut your half-square triangles. Normally you would need squares that are at least 2 ⅞-inch but with this ruler, your fabric strip only needs to be ½-inch larger.
Look at the diagrams below to see how you would use the ruler. It is easy to line up the ruler with your fabric strip, make the cut, and then flip the ruler for the next cut.
Place your cream fabric and the print fabric right sides together. Your pieces are ready to sew!
The blocks will be 9½-inch or 12½-inch unfinished. This is how many River Scraps blocks I have made so far. I have six of the 9-inch blocks and one 12-inch. I’m not sure what I’m going to make. Which size of block do you like?
Four of the 9-inch blocks would make a beautiful table topper.
I have created a worksheet for each of the blocks that you can use in case you would prefer to make blocks in specific colors or just experiment with the blocks. How about a red scrappy block and then a yellow or blue!
Decide how many blocks you would like to make and then figure out how many squares and half-square triangles you need. If you like resources like this please let me know, thanks!
While working on this, I came up with another block that I can’t wait to share. It will coordinate perfectly with this quilt block.

That carpet you see in some of the photos is the outside rug in our gazebo. Mr. Mickey is patiently waiting for me to finish and take him for his second walk of the day!
