## Split Nine Patch Block

The Split Nine Patch block, as seen in the 2019 Quilter’s Planner, is demonstrated in this block tutorial.

### Piecing

Using the 3u2033 squares, make (6) 2 1/2u2033 HSTs, then sew Rows A and B together with a 1/4u2033 seam to make a Split Nine Patch Block. Press seams away from the center HST, then toward the darker fabric.

## How do you sew half square triangles?

## How much fabric do I need for a 9 patch quilt?

## How much fabric do I need for a disappearing 9 patch?

Working with yardage If you’re using fat quarters or yardage, cut them into 5u2032u2032 strips first, then cut the strips into 5u2032u2032 squares. You can get (8) 5u2032u2032 squares from one strip of 42u2032u2032 wide fabric, and a total of (12) 5u2032u2032 squares per fat quarter if you’re working with fat quarters.

## How do you square a triangle?

The general polygon can be treated by drawing diagonals, squaring the constituent triangles, and then using the Pythagorean theorem to combine the squares together.
