I've made a few of those zen gardens out of used items I found at thrift shops and around the house,
@SpiritSong . They are fun to work with and create. Where I used to work, we had a giant one made from wood that was wheelchair accessible with playground sand added to it.
My favorite that I made was for a friend's daughter who had lost her mom to suicide. I found a gorgeous old antique glass ceiling light cover that did not have any holes in it, grabbed a few bags of craft sand at the dollar tree store, and had found a small mason jar full of those little things folks can attach to the crocs brand shoes to decorate them...like letters, flowers, animals, helliday themes, jewels, etc. (like little buttons, almost), and made the rake thingy for it out of a cool looking antique fork, also found at the thrift shop, by bending it at the ends to appear more rake-like. I picked out the different things that reminded me of her mom and when I gifted it to her, sat with her and explained each thing and why I felt it was special. Thanks for prompting that pleasant trip down memory lane. :)
Today, I remembered that I can only change my cell-ph, not others, remembered to breathe on purpose, to go outside and breathe the somewhat fresh air, to stretch my body so it can move a little less painfully, to hydrate healthily before eating dehydrating cooked foods, to chew my liquids and drink my foods, to make my own stuff to ensure I know exactly what I'm getting and the side effects that will follow, and made a few more phone calls to some places to hopefully plant and nurture some more seeds regarding the lack of healthier options they currently make available/affordable to consumers trying to be more mindful of what they consume.
