The technique I chose was stamping and, to further challenge myself, I would use only subdued colours, not my normal brights.
First, as a trial, I created a few stamps, made from the polystyrene trays you get with some foods.
Left is the plain side and right is the back which often has interesting patterns.
I indented the pattern with an empty biro pen point.
Decided to make a journal page called "Still Life".
Made the stamps. I coloured them temporarily with blue so you can see the pattern better.
Here's the finished page
I used metallic pencils and a silver pen to add colour.
The wording at the top was done free-hand.
The stamping was on plain black card using stamping pads.
Tissue papers were painted with watercolour paints for the blue background.
