Last year i pegged them to a garland i made.
And then they ended up in my scrapbook. i use divide page protectors to store them. These are usually used for storing collectors cards, but they're the perfect size for instax pictures.
i don't really feel that i need to accompany the photos with a lot of journalling so i just went with word stickers. i plan to do something similar with this years photos too.
This is what i did this year to display them at the party. It's something i've been wanting to try for a while.
i bought the frame at ikea and removed the back and the glass. Then stapled in the string to hang the photos on to. To make the tags i stamped and embossed a print design directly onto the kraft tags. Then added some Echo Park stickers using double sided tape. Really simple, but definitely a project i love. Plus i can reuse the tags on other Halloween Projects.
