Leather glass case pattern, lined with rolled edges

This is the pattern I use to make glass cases. This pattern has rolled edges. They are tricky to get right, but they allow to line the case with fabric. I use Italian printed silk. The silk is glued using glue sheets.

The pattern has a couple concentric lines. The inner line is where skiving should start (this is the most difficult part). The fabric should be glued at least up to the stitching points.

If skiving goes wrong, you have the option to patch it with some other leather rectangle, like the blue one in these pictures. Or throw it away and start over.
