Nice quilt, did you follow a pattern? I would like to get it if there is one.
I didn't follow a pattern, but sewing this quilt is not very difficult:
You have to cut coloured strips (width: 2,75 inches).
Then you need smaller black strips (width: 1,25 inches).
Then you sew the strips together: black - colour - black.
This new strip is 4,5 inches wide.
Cut squares of 4,5 inches from the strips an arrange them as you like it, always one "up" and one "down".
