Cookie-themed air dry clay coasters

1. Clay cookie – choc chip edition!Air dry clay choc chip cookie on white background

-     Divide your clay block into four equal parts and wrap the unused pieces to keep them soft

-     Roll one piece into a ball and press it over a cork coaster to form the base shape

-     Slice the top slightly to flatten it with a palette knife for a sturdy mug base (save the cuttings)

-     Add textured grooves using the knife, then smooth lightly with a damp finger

-     Roll leftover clay into small uneven chunks for the chocolate chips and press them into the surface

-     Do a quick mug test to check it sits flat, then set aside to dry

 

2. How to make clay sprinklesAir dry clay sprinkle cookie on white background

-     Roll another portion of clay  and cut of a small section (this will be the icing and sprinkles)

-     Press the rest over a cork coaster

-     Use something with a small, rounded edge to press scalloped shapes around the border

-     Trim around the scallops with a palette knife

-     Smooth the edges with a damp brush

-     Roll a small piece of clay for the icing and flatten it into an organic circle shape before pressing on top

-     Smooth with your finger and a little water, then soften the edge using a brush

-     Roll out a very thin rope of clay, cut and roll it into tiny pieces, and press them onto the icing as sprinkles

-     Do a final mug test to make sure it’s flat enough and set aside to dry

 

3. Clay biscuit… but add jamAir dry clay jam drop on white background

-     Flatten another portion of clay evenly over a cork coaster

-     Use a small round object (e.g., cup) to press a circular dent in the centre and remove a little clay to make space for the jam

-     Rough up the texture inside the circle using the back of your palette knife or brush

-     Carve curved lines radiating around the jam and smooth gently with a brush

-     Do a test to make sure your mug sits flat, then set aside to dry

 

4. Now onto the chocolate digestive

-     Press the clay over the cork coaster and roll it flat

-     Draw an 8x8 grid and mark scalloped indents with your palette knife in each grid

-     Soften the divots with a damp brush, reworking any that fade

-     Check that the coaster is flat and smooth before leaving it to dry

 

5. Sealing air dry claySealing air dry clay jam drop cookie with glue and water mix

-     Leave the coasters to dry for 24 hours to 3 days, depending on thickness and humidity

-     Mix equal parts PVA glue and water to make a thin sealer

-     Brush the mixture over the coasters – this will soak in and seal the clay surface

 

6. Acrylic cookie painting

-     Mix a dark umber base tone using white, lemon yellow, orange, scarlet, and black

-     Create a lighter biscuit tone by adding more yellow, orange, and white

-     Brush the darker tone into the crevices of the choc chip and jam drop biscuits

-     Once touch-dry, dry-brush the lighter tone over the top to highlight texture

-     For the jam drop, mix scarlet red with a little medium green to make a crimson tone and apply to the centre of the biscuit

-     Then layer pure scarlet over the jam for extra dimension

-     For the chocolate digestive, combine scarlet, lemon yellow, phthalo blue, medium green, and black until rich and dark, painting over the whole biscuit

-     For the sprinkle cookie icing, mix scarlet and white, then paint over the biscuit top

-     Mix small amounts of white, yellow, orange, green, and blue with white for pastel sprinkles colours, and paint on the small dots

-     Leave to dry completely before use
