cutting the jeans: I cut mine open from front to back to separate the two legs. Next, I cut each leg open along the inner leg seam, to obtain two flat pieces of fabric. I used the top part of each leg to cut the front panel and back panel, the front pockets and back pockets nicely centered. I was extremely careful not to cut the inner pockets to pieces while cutting each panel. That way all pockets are still fully operational! From the lower leg parts I cut the bag's middle panel (2 pieces joined together, about 15cm wide), as well as a strip for the facing of the bag (2 pieces joined together, about 7 cm wide). There was enough fabric left to make handles as well, but I decided to go with leather handles instead.
