I hope you’re ready to play along with the Block of the Month series here on the Polka Dot Chair! This month we are continuing the series with a String Half Square Triangle Quilt Block.
This is block #4 of 12. It builds on the basic HST blocks that we learned to make in October and adds an extra dimension by piecing them from a strip pieced block.
Hi There!! Did you guys have a nice Christmas?? Are you ready to jump back into creating now that the Holidays are over?
Maybe you set a goal for yourself in 2016 to learn to quilt or to complete a specific project? I’ve set a few goals for myself that I’ll be sharing with you in the next few weeks, but before we jump into all of the New Years Resolutions stuff, let’s mark that December Quilt Block of the Month, this String Half Square Triangle Quilt Block, off of our “to do” list shall we?
If you missed it be sure to check out this post offering tips and trick to picking out fabric for a quilt. You can find an index to all the posts in this quilt block series to date by clicking here.

About the Quilt Block:
This months block is a variation of the Half Square Triangle (HST) blocks that we learned to make in October. The variation is that it is made partially with a string (or stripe) block. The block is also set 4 up and I like that it will make the finished quilt look like it’s made up of smaller blocks as well as the larger finished blocks.
How to Make a Half Square Triangle String Quilt Block:
You’ll need to Cut:
- 4 Strips each 2 1/2″ 19″
- 1 Strip 1 1/2″ x 19″
- 2 Squares Background Fabric 8 1/2″ x 8 1/2″
Step One Create the Strip Block:
Stitch your 19″ long strips together with the 1 1/2″ wide strip in the center. Make sure that your seams are precisely 1/4″ and be careful not to distort your seams when you press the strips. Move your iron up and down not side to side.
Trim this block into two pieces each 8 1/2″ x 8 1/2″ (the finished width will be slightly larger than 8 1/2″, just trim the excess)
Step Two: Construct the Half Square Triangles
Next draw a diagonal line on the wrong side of your two 8 1/2″ x 8 1/2″ background fabric pieces.
Place the trimmed strip piece right sides together with the background fabric piece and stitch 1/4″ on each side of the line you drew.
Cut apart along the line you drew. You will now have 2 Half Square Triangle Blocks (HST’s, if you need more help understanding how to make a HST refer to this post)
Repeat for the 2nd set of squares. Make sure that the diagonal line is facing the same direction as it did with the 1st set of squares.
Trim each HST block to 8″ x 8″
Step Three: Assemble the Quilt Block
Stitch the 4 blocks together as shown. Sew 2 blocks in row 1 along the side seams then press. Then stitch the two blocks in row 2 along the side seams and press. Then stitch the two rows together.
Trim block to 15″ x 15″
