Half-Square Triangles

As Easy As…..

I’m always on the lookout for easier and more accurate ways to piece quilt blocks.   In 2010 I took a class with Linda Hunter.  I am finally finishing it.  The only thing left to so are the half-square triangle blocks for the border.

One of my fellow quilters shared one of her favorite methods of making half-square triangles ie.  sewing a 1/4-inch seam around a two blocks, right sides together and cutting the block into fourths.

Place two blocks right sides together

Sew 1/4" around 4 sides of block

Cut into 4-half square triangles

Perfect half square triangles!  The only problem was that I wasn’t sure what size to make the original block to get the 3-12″ finished half-square triangle blocks that I need.

The internet makes answers to questions like this so easy to find.  Christina Lane, The Sometimes Crafter, has come up with an easy formula for creating half-square triangles (divide finished size of triangle by .64)  on the Guest Blogger Series.  Two squares cut 4-3/4″ each produce 4 perfect 3-1/2″ finished half-square triangle blocks.  I always like a ‘bit’ of insurance when piecing so I cut my beginning squares 5″ and had about an 1/8″ to trim all the way around when sizing the block.

The only drawback to this method is that the outside edges of the finished half square triangles are bias edges.  Easy enough to correct though by cutting the  blocks on the bias-no stretchy edges to deal with in the finished block!

There is always time to quilt!
