QOV sent out a "Call of Action" for some 6½ inch Hour Glass blocks.
My friend cut the squares so I made them in no time,
following the method that QOV sent out.
The method used was to cut a print and a background (white) square
larger than the raw finished Hour Glass.
The formula is to add 3/8 inch,
but in our case we used the easier 7½ inch measurement,
then trimmed the final square.
There are several HST (Half Square Triangle) cheat sheets for calculating.
Just search for one.
Then sew as follow to make 4 HSTs.
Place the 2 squares right sides together.
Mark one diagonal line using your favorite method.
Sew quarter inch seam on each side of that diagonal line.
I used a turn table mat to
cut apart FIRST on the diagonal NOT MARKED and sewn.Then ROTATE the mat and CUT ON THE LINE that was stitched on each side.
Then sew together as shown below.
These pictures came from the QOV printout we were given.
I'm not able to find a link to the document.
I really like the QOV quilt over at Katy Quilts.
You can spend a lot of time looking for quilts made with just this one block
in any size you like.
