They are so beautiful and lacy and
It happens in the fall when the leaf is decaying. I hastened the process.
Washing soda is also what you use to make your own detergent. They say it is better ecologically but I think it is the same stuff as you buy in a Tide or Arm and Hammer box, just with a few less scent molecules.
(I use hydrogen peroxide in my washing machine instead of Oxy-Clean since it is just powdered hydrogen peroxide. And at 88 cents a bottle at Walmart it is way cheaper.)
But I digress......Back to leaf skeletons. Where was I?
You get your washing soda and put 4 cups of water in a pot and 3/4 cup of washing soda. Bring to boiling. Drop in your leaves. I have found it works best with leaves that are waxy and stiffer. I used magnolia and nandina leaves and added some ligustrum leaves as an afterthought. The ligustrum and nandina leaves didn't work well at all. Too smooshy. Also, I used fresh leaves not dry ones.
These are the magnolia leaves.
I boiled them for about an hour and a half. There is no set time, you just have to test to see if the cellulose can be scrubbed away. And watch the pot to make sure it doesn't boil away. You may need to add more water and if you do, add more washing soda.
It is not toxic, has no toxic fumes and shouldn't damage anything. It is an ingredient in laundry detergent, soap and dishwasher detergent.
I would also suggest if you want them flat, to press the leaves in a book first for a week or two or three. My leaves were pretty flat when I laid the skeletons to dry on a paper towel.
What you see in this photo is the the texture of the paper towel through the leaf skeleton.
But when they dried they went back to their original shape. Leaf shape.
I want to use them as a mask for printing. Future post!
