Ecoprinting on watercolour paper

I did some ecoprinting a few weeks ago when we had cool weather.  Since then it has heated up.  This morning it has cooled down again so maybe I'll do some more printing tomorrow morning.  Here are some prints I did on 90 lb watercolour paper.  These are 9 X 12 inches.  On the left is a branch of a plant from my garden (not sure yet what) and on the right is a buckthorn branch and some wild grapes I saved in the freezer last fall.

The prints below are maple leaves and tulip petals on the left and tulips and horsetail on the right.
