I often paint and glue my leather parts for the earrings in advance. When I feel like it. Then I use the painted leather when my ongoing design needs it- it can take for a year or a week or just hours. Depends on the flow.
These leather parts I made one summer evening but something more important came along and I put the designs aside. Now when cleaning up my desk and the drawers I found these red and orange leather designs I knew that it was their time to shine.
The fabric is old IKEA curtain.
