JULY 2001
Block of the Month Pattern
BLOCK- Yankee Puzzle using HSTs  (Half-Square Triangles)
For  TWO 12.5" unfinshed blocks

Fabric to Cut:
        16      3  7/8"  squares of medium / dark
        16      3  7/8"  squares of light / lighter

 

On the wrong side of the light fabric squares, draw a line diagonally from one corner to the opposite corner with a pencil.
  
This will be your cutting line LATER
Lay the lighter squares right sides together with the dark squares.  You should have 16 sets now.

Measure (and draw, if needed) scant 1/4" from the marker cutting  line and stitch the light to the dark using a 1/4" seam allowance.  Turn fabric and stitch scant 1/4" from marked line on other side.  Do this for all 16 sets of squares.
Chain stitching works well with this procedure.

cutting line for AFTER sewing
Cut each stitched square on cutting line. Finger press the seams flat on the right side of the seam and press seams to the dark fabric side.  You should now have 32  HSTs (Half Square Triangles).

STEP 3

With all seams pressed toward the darker fabric, arrange 4 HSTs into 1st row. 
Stitch HSTs together on side seams  that will touch making sure right sides are together and order is maintained  -  Always use 1/4" seams

STEP 5
Once the skill of making HSTs is mastered..... many arrangements and designs are available to make with a simple arranging of the HSTs.
The possibilities are endless!!!
Cut 16 of each color
You will use 16 HSTs for each 12.5" unfinished block
Arrange 12 other HSTs into
Rows 2, 3 & 4 as shown and stitch the touching seams as done in Row 1
Lastly, with all the seams again pressed, sew the rows together in pattern to maintain the design shown. 



Notice the pinwheel in the middle....imagine now making that a different color than the outer HSTs and the whole block changes AGAIN! 



And all with 3 7/8" squares!  these little HSTs can be turned every which way!  Have Fun!
