Make a pattern for your quilt. Here, the scribbly things represent the star-patterned flannel, the circles represent the dark blue flannel, and the triangles represent the grey chevron-patterned flannel. The quilt will be 5x6.
Cut your pieces. They should be 8 1/2 square inches each. This will take a pretty long time.
Take a square of backing, a square of batting, and a square of patterned flannel and lay them in a sandwich. The right sides of both the backing and pattern should face outwards.
Sew around each square, with a margin of about a half-inch. It's okay if it's not a perfectly even margin, though.
Sew the squares together, lined up with the patterned sides facing outwards. Sew them along the lines that you sewed each individual square on, and follow the pattern you drew up.
Sew them in one long strip until you have either 1/5 or 1/6 of your quilt (depending which direction you sewed). Repeat step 5 until you have sewn all the strips.
When you sew two strips together, make sure to sew the extra flat, like in the picture. This helps with cutting the fringe.
Now you have a quilt! The next step is to cut a fringe into the edges. Cut about 1/4 inches apart, and only cut in one direction at the join of 4 squares to prevent it from becoming lumpy. Then wash, and you're done!
