Insta-Blocks: "Magic Eight" Triangle Squares!

How to make multiple HALF- and QUARTER-SQUARE TRIANGLES all at once!

PLUS a little "Quilter's Math"

To determine the size of squares you'll need to cut for

Eight INSTANT HALF-SQUARE TRIANGLES = (FS + 1") x 2

(Desired FINISHED SIZE + 1 inch) x 2 = Cut 2 squares

HALF-SQUARE TRIANGLES
    1)  DRAW an "X" on the wrong side of the lighter fabric.

2) LAYER with right sides together.

3) STITCH on both sides of each line.


4) CUT vertically, horizontally +, then diagonally x.


TRIM, PRESS.  YIELD: 8 Half-Square Triangles

To determine the size of squares you'll need to cut for

Eight INSTANT QUARTER-SQUARE TRIANGLES = (FS + 1.5") x 2

(Desired FINISHED SIZE + 1-1/2 inches) x 2 = Cut 2 squares

QUARTER-SQUARE TRIANGLES

Follow steps 1 through 4 as diagrammed above, then press HSTs open

with seam allowance toward the darker fabric.  Continue as follows:

Use two Half-Square Triangles.

1)  DRAW a diagonal line on the back of one of the HSTs,
perpendicular to the stitching line.


2) LAYER two HSTs together, abutting the seam.


3)  STITCH on both sides of the line.


4)  CUT on the drawn line.


YIELD:  2 QSTs

TRIM, PRESS.

REPEAT with each set.  One batch of Matic 8 HSTs will also
YIELD 8 Quarter-Square Triangles.  The Ohio Star block uses 4 QSTs.

Happy Quilting!
