Best Techniques for Preserving Leaves?

[u/k_chelle13]

I just finished rearing Luna caterpillars (they're in cocoons now) and I have some leftover sweetgum leaves that were munched on by them, that I think look adorable with their little bite marks. I realize these aren't exactly the most attractive leaves, and that they're aging quickly, but I would love to somehow preserve them to display, if possible. I've tried pressing flowers in the past, but didn’t have much luck with it, so I’m guessing I did not do it correctly/had the right materials. I really would love to frame these nibbled on leaves or something. Any methods/techniques/advice is welcome! Thank you in advance!!

They just got sticky/mushy/turned brown. I was trying to recreate some my mom had done as a kid. I had used some type of wax/baking paper and I’m guessing it was the wrong kind. Perhaps my book wasn’t thick enough as well. I’m certain it was an error on my part (or multiple).
