This lesson taught us how to insert a zipper into our book to give a place to peek at something hidden. You need 5 pages in your book to do this. Stick together pages 2 and 3 and 4 and 5 then decide where you want the zipper to go according to your layout and cut a slit 1/4" wide out of the stuck together pages 2 and 3. Decorate the front then attach zipper to the back of this with sticky tape, mine was not strong enough to hold the zipper when opened so I added some E500 glue which did the trick. Attach the item you want to hide onto page 4 and then run a strip of sticky tape along the bottom edge and right hand side only of page 4. This way when the zipper is opened you can curl back the opening to reveal your picture. As you can see from the following picture once again my double sided tape failed me at the top.
I added a hand embossed copper sheet crown and corner pieces and a strip of red metal sheet with the words Copper Candle Sconce across the bottom right diagonally.
This technique is very fiddly and you do need strong glue but it is well worth the effort when it is finished, adds a cool new dimension to your book.
