How To: Make Two Half Square Triangles at Once

Wednesday, June 24, 2015

You can do some pretty amazing things in the quilting world, just by sewing straight lines. Well, cutting and sewing straight lines. It's actually fairly easy as a beginner to create some stunning quilts simply using squares and right angle triangles. These are just a few examples of quilts I adore...and use only rectangles and half square triangles.

One of the basic building blocks of most quilts is a 'half square triangle' (the most basic being squares and rectangles). An 'HST' isn't too tricky. I borrowed the directions from about.com. These instructions will make two half square triangles at a time. If you'll be making more than that, try Craftsy's eight HSTs at a time tutorial.

You can do this. I'm a sloppy quilter, and everything turned out okay. It'll turn out okay for you, too.

  1. Cut two squares, finished size + 1" (in my case the finished size is 5", so I cut two 6" squares)
  2. Draw 45 degree line across wrong side of one fabric square
    HSTs 1: Draw 45 degree line across square
  3. Squares, right sides together
    HSTs 2: Squares, right sides together
  4. Sew 1/4" seam along one side of line
    HSTs 3: Sew 1/4" seam along one side of line
  5. Sew along other side of line
    HSTs 4: Sew along other side of line
  6. Cut squares along drawn line
    HSTs 5: Cut squares along drawn line
  7. Iron seams open
    HSTs 6: Iron seams open
  8. Trim seam allowances
    HSTs 7: Trim seam allowances
  9. Cut square to desired size, seam connecting corner to corner

MAKE MOAR HALF SQUARE TRIANGLES.
