Here it is, looking very comfy on my un-finished Granny Stripe. The process is a little time consuming at the beginning, setting everything up but I promise it is well worth it. I've used 5 different fabrics here:
Corners:
1. Take fabric's a and b and cut a strip of each measuring 7" x 3.5" / 16cm x 8cm
2. Cut the strips in half to make squares measuring 3.5" x 3.5" / 8cm x 8cm
Middles
3. Still using fabrics a and b, cut a smaller strip measuring 5" x 2.5" / 12cm x 6cm
4. Cut these strips in half to make small 2.5" x 2.5" / 6cm x 6cm squares
5. Take fabric e and cut a square measuring 5" x 5" / 12cm x 12cm.
6. Cut in four equal smaller squares measuring 2.5" x 2.5" / 6cm x 6cm
Sides:
7. Take fabric d and cut a strip measuring 14" x 7" / 32cm x 15cm
8. Cut into 4 equal pieces measuring 3.5" x 7" / 8cm x 15cm
Triangles:
9. Take fabric c and cut a strip measuring 14" x 7" / 32cm x 15cm
10. Cut into 8 equal squares measuring 3.5" x 3.5" / 8cm x 8cm
Seams:
11. Draw a border around each piece 0.25" (1/4") / 0.25cm from the edge.
Making up the triangles:
12. Take one piece of fabric c and lay it on top of a piece of fabric d. Draw a line diagonally from the top middle to the bottom corner
13. Sew diagonally down the line.
14. Fold the triangle back and press.
15. Repeat for the opposite side.
16. Do this for the remaining 3 sides.
17. Stop for some cake. This step is very important!
Making up the middle:
18. Take 3 small squares of a, b and e.
19. Turn over and sew down the seam lines.
20. Repeat with the remaining middles to make a pattern like this:
b e a
e d e
a e b
21. Sew all three strips together.
Making up the sides:
22. Take the triangle pieces and attach the larger squares of a and b to the ends, alternating with a at the top of one piece and the bottom of the other.
Those of you with a keen eye will notice I have sewn the ends on wrong here! I un-picked and re-sewed them but forgot to take a photo!
Final assembly:
23. Sew the remaining two triangle pieces to the middle square
24. Then sew the sides to the middle.
25. Almost time for a cup of tea! Now time for the back. I usually put zips on my cushions but you need an extra wide seam at the bottom which I forgot to do. I have opted for a flap instead and may put buttons on it at some point.
26. Lightly press. Now definitely time for a brew!
This is a modified version (only slightly) of this tutorial on About.com. I found the sizes they gave were a lot bigger as it was for a quilt and not a cushion, so I have reduced things down a little.
