Collect leaves of various shapes and sizes, and use only the best specimens. You'll need fabric paints in fall colors, such as brown, dark green, and deep red. You can customize your own colors through blending the paints.

To make your tablecloth design, experiment by moving the leaves around on the fabric. You can create a border, but covering the entire tablecloth with leaf prints is also lovely.

Materials
Sponge brushes
Leaves of various sizes and shapes (make sure they are not brittle)
Fabric paint
Light-colored cotton or linen tablecloth, prewashed
Paper towel, parchment paper, or kraft paper
Brayer or rolling pin
Iron
Muslin or scrap fabric (optional)

1. Use a sponge brush to lightly coat the veined underside of your leaf with fabric paint.

2. Place the leaf, paint side down, onto the tablecloth. Cover the leaf with kraft paper, parchment paper, or a paper towel to prevent the paint from getting on the brayer or rolling pin.

3. Roll the brayer over the paper a few times, firmly pressing the painted leaf onto the fabric. Keep the paper as still as possible; if it shifts, the paint beneath the leaf will smudge. Lift up the paper and the leaf.

5. Before heat-setting the paint, wait 24 hours. With the pattern side down, press the cloth with an iron set at medium high. Protect your ironing board by covering it with a piece of muslin or scrap fabric first.
