Trace the triangle template given in the pattern and cut it out. Tape it to the backside of a ruler as shown. This will help you cut the corners on the A and B pieces.
Position the triangle taped on the ruler in the corner of A/B.
Cut the corner off. You will do this on all As and Bs.
Lay a C in each cut corner of all A/B pieces and sew a 1/4" seam allowance.
Fold all Cs back and press.
Trace a star for all A/B/C units onto fusible produce and fuse to the wrong side of the star fabric.
Cut all stars out and fuse to the A/B/C units. Stitch/appliqué down.
Sew all A/B/C units together (according to each row). I pressed my seams open.
This is a view of the top border.
Sew a D to each end of the border. Press toward D.
Final view of the top border. Repeat for the rest of the star border. D is sewn only to the top and bottom border or the side borders, but not both. Once these are made you can sew it all together and you're done!
