There are many ways to display a quilt - the most common way with a sleeve on the back, with triangle pieces at the upper corners, on a canvas on a frame.
This time I will show you how to use a box as a frame. There are many sizes in IKEA. Or you could order different size.
The first step when you have already a box is to mark the place of the quilt on the "bottom" of the box. Simply use a pencil to mark the four corners.
Then drill two small holes inside the mark at the first corner..
Proceed with the next corners.
Sew the quilt at the four corners with coordinating thread and tie on the back.
