From bright print, cut three 3-1/2x5-1/2" rectangles.
With right side of fabric up, fold one long edge of a print rectangle under 1-1/2"; press. Repeat with a second rectangle.
With right sides facedown, overlap folded edges of rectangles 1/2". Place remaining rectangle right side up on your work surface, then position overlapped rectangles on top so right sides are together; pin.
Using a 1/4" seam, sew together and turn right side out to complete tissue-pack cover. Insert tissue packet through opening.
