No, not THAT kind of memory. 'Fraid I don't have any real solutions for that.
But I do have creative ways of saving mementos from our trips together before storing them in my precious Stagecoach Box. For example,look how I dress up the notes I take while we travel.
I tuck them into envelopes I fold from handmade paper and decorate them with paper ephemera and the occasional chimpanzee. I get the ephemera at flea markets or at online suppliers like Regina's Studio.
The chimp was just here.
Paper emphemera also comes in handy for more free-floating storage in the box's nooks and crannies.
You can use fabric as well as paper. I use those failed sewing projects to store the rusty bits I find underfoot in ghost towns.
I square off the fabric block into a rectangle and sew it into a small bag (need directions?), attach a drawstring and label and voila, the failure is now a success.
Some mementos need to be seen. That's where my trusty hot-glue gun comes in.
The lid of the box is just the beginning. Other people collect old glass bottles. As you can see here, I prefer them a bit more weathered.
I don't always need a container for my mementos. With a little hot glue, the mementos themselves can become the container!
I understand that not everyone saves rusty nails or glass shards. (Well, I don't understand it, but I accept it). We'd love to hear how you make your memory boxes special on the inside as well as on the outside.
