Hi!! Here is another tutorial for a realistic opal and wood box using a mint tin, polymer clay, iridescent micro glitter/flakes and water color paints. If you would prefer to watch the step by step video you can find it here: https://www.youtube.com/watch?v=iM-fm8TSkPw
#1 Add iridescent glitter flakes and/or micro glitter to translucent polymer clay.
#2 from that clay subtract a small chunk and divide into 4 smaller pieces.
#3 Add a tiny hint of water color paint to each. I used a blue, purple, green and red (pink) and mix paints into clay.
#4 flatten those pieces into another small chunk of polymer clay and flatten out, then fold over 1 time and flatten again.
#5 Cover with remaining clay and flatten out large enough to cover the top of tin.
#6 Add a small amount of liquid clay to the top of tin, then press your clay on top of tin.
#7 Pre-bake in oven for 5 min at temp specified on your polymer clay package.
#8 Make faux wood layer by rolling out 4 different shades of brown into logs. Enough clay to cover the bottom of tin. You can color white clay with water color paint as I did or use pre-colored clay.
#9 Press together the logs and flatten.
#10 Cut, flip, flatten until an interesting pattern is achieved, then scratch up surface with a fork.
#11 Add another small amount of liquid clay to bottom of tin and press on clay.
#12 add additional detail with a sculpting tool or safety pin.
#13 Fully bake according to instructions on your polymer clay package.
#13 (optional) I cut a small piece of cardboard and glued on fabric to use for bottom.
