1 pattern to a make a 3 yard, lap size, quilt.
You will need 3 coordinating fabrics, 1 yard of each.
Thread to match.
3 yards of fabric for the backing and a twin size batting to finish this quilt.
You also may want to get an extra 1/2 yard of fabric for the binding. These patterns have economy binding factored in but if you like the conventional 2 1/2 inch strips for binding then you need to purchase a little extra fabric for that.
