- Creating the slabs of acrylic can be done any time the paint is available. Large slabs will take 3 days to
dry depending on the thickness of the paint and the room temperature. Cookie sheets with sides work well to
contain any flow of paint.
Tear a piece of parchment the length of the cookie sheet. Pour the liquid acrylic
onto the paper. Do not dilute the acrylic or use paint that is thin. Colors can be combined. Use the spatula
to spread the paint to about 1/4" thickness. Paint does not have to be a consistent thickness or have even
edges.
Place the cookie sheet in a window or where air circulates. As the paint dries, the paper will wrinkle
and create waves, swirls and bubbles in the slab. The more texture the merrier!
- When dry, gently peel the slab off of the paper. Each released slab may be stored on the paper until
needed. NOTE: Do not use wax paper as the slab will stick to it.
- Create a design and draw it loosely on the matboard surface as a guide. Wood works well as a backing
also. The design must be simple but can include curves as well as angles for movement. The design can be
vertical or horizontal. The "shingles" are applied in an overlapping technique.
- Choose the slab colors needed. Use a 12" ruler to mark a line the width of the slab. The lines should be
1/2" to 1" wide depending on the size of the design. Cut on the line with scissors. Cut only the number of
strips needed to get a start. Using the scissors, cut strips into "shingle"-like pieces. Save all extra pieces,
even the uneven edges as they are good for additional texture. Keep pieces on a sturdy plastic dinner plate
for a palette of colors to be used.
- The "shingle" design is created by starting with the bottom of the design. Glue the first pieces on the
lowest part. Add more "shingles" on top overlapping the first layer and working upwards. Use a generous
amount of glue on the top and back edge of each piece. Use the same method on curves and angles.
