Half Square Triangle Blocksby Joanne M. Winn
The formula for Half Square Triangle Blocks ----- finished size + 7/8"
e.g.  2" finished square (used in the Christmas Star Table Topper) is 2" + 7/8" = 2 7/8" cut
squares

Cut
1  -- 2 7/8" square of light or background fabric
1  --  2 7/8" square of print fabric
Press with right sides together and all edges even.
Draw a pencil line diagonally from corner to corner - Fig 1
Stitch on each side of that line with a scant 1/4"   Fig 2
Press flat
Cut on the drawn pencil line
Carefully press seams open (unless the print will really show through - then press to the print)
Do not rub your iron back and forth or have the heat set on high.
This will give you 2 perfectly pieced squares.  Fig 3
Each of the 4 blocks for Christmas Table Topper requires 2 perfectly pieced squares.

Quarter Square Triangle Blocks
The formula for Quarter Square Triangle Blocks ---- finished size = 1 1/4"
e.g. 2" finished square (used in the Christmas Star Table Topper) is 2" + 1 1/4" = 3 1/4" cut
squares

Cut
1  --  3 1/4" square of print fabric #1
1  --  3 1/4" square of print fabric #2
Press with right sides together and all edges even
Draw a pencil line diagonally from corner to corner  Fig 1
Draw a second line diagonally from corner to corner on the opposite corners  Fig 2
Stitch with a scant 1/4" on each side of one of these diagonal lines  Fig 3
Press flat
Cut on the diagonal line that does not have the stitching on each side of the line
Now cut on the pencil line that does have the stitching on each side of it
Gently press seams open
I like to make several sets before I go on to the next step - for variety in the prints
Pin at the center seam of two sets of triangles lining up the center seams
I also like to pin the two ends of the triangles so that they cannot run off when you sew them.
Tip -- hand wheel the needle or use needle down to put the needle down into the hole - lift the
pressure foot and insert the triangles holding on to the pin to keep it straight.  Take a few
stitches and remove the pin.  Hold the bottom pin taunt until you get close to it and then remove
it and stitch right off the triangles.
Gently press seams open and check for accuracy.

Two 3 1/4" squares will make 2 perfectly pieced Quarter Square Triangle Blocks Fig 4
