Did you guess correctly?  Have you worked out the pattern?

Again, there is more than one way to make Quarter Square Triangle blocks, choose the method you are most comfortable with.  Once again, our unfinished block size is 6 1/2″.

This method creates two quarter square triangles. We are cutting our squares bigger and will trim down to size.

To create a 61/2″ block (unfinished):

Two squares of fabric 71/2″

On one piece, draw a line from one corner to the other diagonally.

Lay both rights sides together and sew 1/4″ either side of the drawn line

Cut along the drawn line and press your blocks open.

On the wrong side of one piece, again draw a line diagonally across.

Place the two half square triangle blocks rights sides together.

Again, sew either side of the drawn line using 1/4″ seam allowance.

Once sewn, cut along the line, and press pieces open.

Square up block using a 6 1/2″ square ruler, using the 45 degree diagonal lines to help. They should run along your seam lines, with the centre intersection on the centre of your block.

I’ll see you again tomorrow for block 5.
