    Step 1

    Gather your supplies.

    Step 2

    Make your ball of clay into a wedge shape.

    Step 3

    Set the slab roller to 1/2"

    Step 4

    Roll the clay through the slab roller.

    Step 5

    Turn the clay so the long edge is against the roller.

    Step 6

    Set the slab roller to 1/8".

    Step 7

    Roll the clay through again.

    Step 8

    Take the clay back to your table and smooth it with a metal rib.

    Step 9

    Flip it over.

    Step 10

    Smooth the other side with a metal rib.

    Step 11

    Step 12

    Cut 4 "A" pieces from the pattern. 4"x4" square.

    Step 13

    Cut 2 "B" pieces. 4" x 3 1/2" rectangle.

    Step 14

    Try to minimize the space by placing your patterns down and tracing before cutting. Put pieces side by side if necessary.

    Step 15

    Cut out the pieces. Keep the sides as straight as possible.

    Step 16

    Stack pieces with paper in between them. Allow pieces to become leather hard before building.

    Step 17

    Scrap clay can be wedged to use for building and decoration.

    Step 18

    Wedged clay and stack are wrapped in plastic over night.

    Step 19

    When clay is leatherhard, take an "A" side and slip and score on side.

    Step 20

    Take another "A" side and slip and score the edge.

    Step 21

    Gently but firmly press the edge on one "A" side to the top of the other "A" side.

    Step 22

    Stitch the two pieces together with a wood tool.

    Step 23

    Add a moist snake of clay to the joint do the two pieces.

    Step 24

    Smooth coil to seal the joints.

    Step 25

    Take a "B" piece and slip and score two edges and the sides of both A pieces.

    Step 26

    Gently but firmly press the B piece to the corner of the two A pieces. Stitch the B piece in.

    Step 27

    Smooth the outside of the attachment with a metal rib.

    Step 28

    Repeat on the opposite side with the other B piece.

    Step 29

    If slip oozes out, scrape with a metal rib.

    Step 30

    Stitch the B piece to the A pieces.

    Step 31

    Add a coil and smooth.

    Step 32

    Smooth all the joints before attaching the last two pieces.

    Step 33

    Slip and score another "A" piece on the edge and two sides. Slip and score the place where it will attach on the box.

    Step 34

    Press gently but firmly so that the two A pieces sandwich the B pieces.

    Step 35

    Stitch the pieces together and smooth in a coil.

    Step 36

    Take the last A pieces and slip and score the sides. Slip and score the edges of the box where the A piece will attach.

    Step 37

    Firmly but gently press together.

    Step 38

    Smooth with a metal rib so that the seams are invisible.

    Step 39

    Smooth edges with a sponge; everything should be round and smooth.

    Step 40

    Keep smoothing.

    Step 41

    Attach a decorative topper and decorations to the sides.

    Step 42

    Draw a line around the box to mark where the lid will be cut.

    Step 43

    Using the knife, carefully cut through the clay all the way around.

    Step 44

    Make sure your cuts are clean and even.

    Step 45

    Stitch and smooth the inside of the top.

    Step 46

    Smooth all the edges with a sponge. Be careful not to change the shape so the lid fits back on.

    Step 47

    Use a paper towel to keep the lid from sticking to the box as it dries.

    Step 48

    Check to make sure the lid fits well.

    Step 49

    Allow to become bone dry before firing. Glaze and fire again!
