This really doesn't take a long time to do! This is a fun craft to do with a friend.
To make a Spirit box, get any box with a separate lid. It can be as large or as small as you like. You just need to make sure that it can hold several pieces of torn or folded paper at a time.You can also do this with a jar. You should decorate the box, but feel free to use any/all materials you wish. It can be simple or quite elaborate. If I'm using a paper box, I decorate both the inside and the outside. To do a jar, I just do the outside. I use paint, rubber stamps, glitter (always glitter!), cut out pictures from magazines, printed tissue papers (especially for the jars). I might glue on beads, ribbons, feathers, shells, and/or acorns. There are no rules or right way to do this! The goal is to have fun, and not stress out about the results!
For adhesive, I recommend using Mod Podge. You can also use white Elmer's glue, thinned out a little. Mod Podge is nice because you can seal your work when you are done by brushing on a coat all over the box. It also comes in a sparkle version. If you want to pile on beads or other attachments, Golden Regular Gel Medium is good. You can press the beads into it and it will harden nicely. There are lots of different craft glues on the market, so you can just use your favorite. Let the whole thing dry overnight, keeping the lid separate until it's dry.
So, you've just made a Spirit box! To use, just write out your problem on paper, read it out loud, and ask your higher power for help in solving it. Put the paper in the box and put the lid back on, and forget about it! I keep my Spirit jar on my altar. It's good to occasionally clean out the box. Don't go back thru and read everything! Just dump it! I burn the contents of mine outside in the fire pit. I hope you have fun making your Spirit box! I'd love to see photos of yours when you get done!
