Sewing Directions:

Half Square Triangle Units:

Step 1:

Using the Light/Ivory 5" squares and Dark/Purple 5" squares, sew together four Half Square Triangle (HST) units as shown in the picture below. Trim/square up the units to 4.5" square.

Be sure to put the Light/Ivory squares adjacent to each other (and the same for the Medium/Tan squares).

From here the block goes together just like a Nine Patch block. First you sew the units in three rows.

The Hidden Star block was really quick to sew together. With only HST and Square in a Square units and a square, it makes for a great block for beginners. You could play with different color combinations like switching the placement of light and dark fabrics, or substituting the light half of the HSTs with another (fourth) color fabric.
