Sewing Directions:

Half Square Triangle Units:

Step 1:

Using the Light/Ivory and Medium/Peach 5" squares, sew together four Half Square Triangle units as shown in the picture below. Press the seam allowance toward the Medium/Peach fabric. Trim/square up the units to 4.5" square. You can find a tutorial for making a basic Half Square Triangle block at

Four Patch Units:

Step 2:

Next make five Four Patch units using the Light/Ivory and Dark/Green 2.5" squares as shown below. You will find my tutorial for making Four Patch blocks in all sorts of different ways at I pressed my seam allowances using the tweak/twirl/furl method.

The Jacob's Ladder block went together super fast! There are so many variations of this block from using just a light and a dark fabric to turning the Half Square Triangles and/or the Four Patch units 90 degrees. You could really have fun playing around with this block.
