Block Basics: Half-Square Triangles – 2 at a Time

If you’re here to put together our Beginner Skill Builder Sampler Quilt, welcome! This is Month 1, Week 1, and I’m glad you’re here!

If your just here to learn how to do 2 at a time Half-Square Triangles, you’re in the right place too.

Half-square triangles (HST) are very versatile and simple, and a great way to start your quilting journey.

Cut List

  • 1- 4” x 4” background fabric
  • 1- 4” x 4” colored fabric

Draw a diagonal line in the lighter fabric from one corner to the opposite corner.

Sew 1/4″ down each side of the diagonal line.

Cut down diagonal line.

Press toward dark fabric and trim to 3 1/2” square.

And you have 2 half-square triangles (HST).

If you’re here for the sampler quilt, you’ll need to do two different sets: 2 of one color and 2 of the other, like below.
