HST Tutorial

In a July 20, 2011 post, I showed you a quilt I made which included MANY half square triangles, or HST's. I made the quilt top in a class taught by Roxann O'Hare of The Cosmic Cow.


In that class, I gained confidence using the oversized square method for constructing half-square triangles (HST's), pictured above in a mini-tutorial.  Here are the steps:


Join two oversized squares (I used a 7" square to create a finished 6" block for a charity quilt project).

Draw a line, corner to corner.

Stitch ¼" from the line on each side of the line.  (Sewn line – drawn line – sewn line.)

Cut on the DRAWN line, leaving two triangles.

Press the seam to the dark side of each HST.

Trim to your desired size.  If you have a ruler with a 45 degree angle line, that's super helpful. You can align that line with the center line of your block before cutting.


Voila!  Perfectly-sized HST's. 


Yes, it uses a bit more fabric, but the increased accuracy and decreased frustration are worth a few extra pennies, I think.  With perfectly-sized HST's and a ¼" foot on my sewing machine, I'll be happier with my finished blocks, and my trusty seam ripper can spend more time in the sewing box!
