One of the last things I did when I worked at Columbia was mounting sheets from an herbarium. I love these old specimens, taped flat to support sheets, especially when labels are handwritten.

I've been pressing flowers and foliage in my book press for months now, between blotter and Bondina (nonwoven polyester), under whatever conservation or binding work is in there.
