*Note: Half squares triangles (HST) allow plenty of room for trimming. To make HSTs with some trimming space, reduce square size by 1/4". To make HSTs without trimming space, reduce square size by 1/2". 

Pressing: Always press to the dark fabric unless otherwise noted.

Assembly Instructions

Step 1: Make the HSTs. Lay the large color fabric square on top of the large white fabric square right sides together. Mark a diagonal line along the squares, then sew 1/4" away from both sides of the line. Refer to the next 3 photos.

Cut along the line. Press open and trim to the proper size for your desired block size. See next two photos.

Step 2: Make the star points. Lay a HST on one of the larger of the remaining color fabric squares right sides together. Mark a diagonal line along the squares perpendicular to the seam of the HST. Sew 1/4" away from both sides of the line. Refer to the next 4 photos.

Cut along the line, them press open and trim to measure the proper size for your desired block size. See the next two photos.

Repeat this to make a total of 4 star points.
