Every November Mom would gather autumn leaves in Discovery Park and wax them for me. I'd use them to decorate the Thanksgiving table. Several years ago, I asked her to teach me. We took an outing to the military cemetery in the park, a site for amazingly large, yellow maple leaves. Then she taught me how to dip them. Properly.
Waxing leaves is quite easy. What's hard is resisting the temptation to get the wax too hot. Mom cautioned against this but mostly from the standpoint of risk..."a real fire hazard", she warned. What I learned is that wax that's a bit too hot burns the leaves; they lose their original color and crinkle up on the edges. Oh well, they still look pretty good and I'll use them this Thanksgiving.
