For this pillow, you will need 1 charm pack, or (8) 5" squares & 20" of white fabric.
Fabric used in this tutorial is Sweetcakes from Riley Blake Designs and can be purchased here.
Select 8 squares for your colored pieces. I matched them in sets of 2-- (2 red, 2 patterned white, 2 pink, 2 blue). Each set will make one row.
Cut (32) 2 1/2" squares from your white fabric.
Mark each square diagonally as shown below.
Subcut each of your 5" patterned squares into (4) 2 1/2" squares. This should give you (32) 2 1/2" squares.
Pin each patterned square to a white square.
Sew down both sides of the line in a 1/4" seam. See picture below for illustration.
Using a straight edge, cut between the 2 seams. Repeat for all 32 squares.
Press seams open. You should have 64 half square triangle blocks.
Arrange blocks in rows to make a chevron pattern.
Repeat for remaining rows.
Sew blocks together to make rows.
Then sew rows together to make the pillow front.
I prefer if all my pillows are sewn as slipcovers so they can be easily removed and washed. I have kids, people. So at this point, I need to make it fit a standard pillow form size. (12", 14", 16", etc). I sewed a 1 1/2" white border to each edge of the pillow front, then trimmed it to a 14 1/2" square.
To make the back of the pillow, cut two 10 x 14 1/2" pieces from your white fabric.
Hem one 14 1/2" side on each piece as shown below. (1/2" fold, then 1/4" fold)
Pin and stitch down on both pieces.
Pin one piece to pillow front, with right sides together.
Pin second piece down. This will overlap the first piece by about 4-6 inches.
Stitch in 1/4" seam completely around the edges, backstitching over the overlapped sections for extra reinforcement.
I like a finished edge, so I zigzagged for a clean finish.
Turn inside out and insert your pillow form.
