Choose a frame large enough to display the doily.
Choose a fabric in a contrasting color to the doily to cover the cardboard in the back of the frame
Remove the back of the frame.
Remove the cardboard from the back of the frame and cover tightly with fabric, cutting off excess fabric.
Secure the edges of the fabric to the cardboard with tape or glue, if desired.
Position the doily on the fabric as desired. You may display the entire doily or only a portion of it.
Hold the doily in the desired position, flip the cardboard over and place into the frame.
Replace and secure the back of the frame. If the doily does not fit snugly between the glass and cardboard after the back of the frame has been replaced, remove the back of the frame and secure the doily to the cardboard with a few pins or drops of fabric glue.
