Been playing with this for the past few months. Got a papier mache elephant from Spotlight, covered it with metal tape.
For texture and colour I used:
typewriter to type on some of the tape with Steam engine related text (inpsired by a vintage physics book)
inscribed some physics diagrams with a embossing tool. *rubbed inks into the tape to bring out the detail and also dripped alcohol inks to make rusty marks *Tape transfers on the back of the metal tape with laser copies for the Victorian lady and gent, and factory image on front of elephant (flipped in photo editing software so writing wouldn’t be backwards). Plus a few other metal tape tranfers of vintage photo images.
Tried embossing rubber stamped images onto metal tape without success so ended up stamping and embossing onto white tissue paper then using inks to distress before attaching with decoupage glue. Worked really well. Rubber stamps from Darkroom door and an ebay store that sells Victorian type images.
Also some glued on scrapbooking elements from Graphic 45, various other scrabooking glittery bits, couple of rubons of keys and clocks, plus a bit of dimensional glaze on the faux plaque.
Last step was a coat of varnish, then attached chains, a little lady with some brads to make her legs move (from Graphic 45)
Oh and a couple of Mica splittings with some images stamped in black ink and eyelets set are hanging on the chains, plus a vintage pen nib.
