My Scrappy quilt I finished by turning the front over to the back, which is easier than binding a quilt.
First I used a ruler and marked a line all along the quilt as a marker to turn the top fabric over.
Next I turned to top fabric over and pinned the three layer together.
Once the pins where all in I trimmed round the edges leaving the quilt as shown below.
Once trimmed I took the pins out, turned the quilt so the back is on the top.
Pin the top fabric in place, then sew in place. Finished photo to follow.
