Pick some of your favorite seeds either ones that you have collected yourself or bought somewhere else
Put them all together in a container such as a bowl or tupperware, anything clean and dry.
You can also separate your seeds, I just combine them for a more natural look. You can choose plants that grow well together or not but just make sure they have just about the same germination rate
You want to use both clay soil and organic compost in your mixture, a little compost to mix in the clay to help store organic nutrients in each ball for the seedlings.
Depending on how much you want to make, the recipe will include different amounts. Generally it's 5 parts clay, 3 parts organic compost, 1 parts of seed and 1-2 parts water, depending on your use.
The input of the seed is different for everyone. You can put a small hole in the center and place the seeds inside. Or half your ball in hand, add seeds and then cover. Or even combine it all!
This is multiple seeds that I squished into one side, then covered with another chunk of soil.
This is an example of one seed in the center, then I closed it up!
They kinda look like meatballs when your roll them, you don't usually have to make them this big. Most are smaller than a golfball or about the size of a cherry. After rolled, I dip them in water.

And pinched closed.
Again, they don't have to be this large, I just chose this size. I also made smaller cherry sizes as well.
Once they are rolled into balls, I dip them in water for a brief moment and then roll them in compost for a little extra ...it is not necessarily needed to finish.
Your hands will get dirty if you are doing things right!! And you will most likely enjoy it, I did! Now get out there and start playing ...the sooner you do, the sooner you can do some seed bombing!
Once you are finished, try to lay them out on a sheet or something flat where they can dry for about a week or so. Maybe sooner depending on where you live. You just want them to be dry and solid.
