Measure the length and top width of one side of your square lampshade and divide each measurement by two. Use these measurements to find the exact center of this side of the lampshade.
Using the measurements you just made, lightly mark the center of each side of the lampshade with a pencil.
Use the central pencil mark you just made to center your floral stencil on the lampshade. Tape down every side of the stencil securely.
Paint directly over the stencil with stencil sponges using at least two different colors but no more than five. Let paint dry for a few hours before gently peeling off the stencil. Repeat on all sides of the lampshade.
Outline the flowers with a thin line of hot glue and quickly pour seed beads over the glue before it dries. If desired, outline the leaves with glue and beads as well.
Glue the beaded fringe along the bottom edge of the lampshade. Use considerably more glue than for outlining the floral pattern.
