How to press poppies
Here's what I've been doing today... pressing some of my really big (long?) scarlet poppies, along with their stems and leaves.
I'm pressing the flowers in my Microfleur, and the the 9-12" stems in a larger wooden microwave flower press, and the longest stems are being pressed in my "mega press".
I'm leaving most of the leaves right on the stems, but I'm also pressing some separately as well. Poppies hold their red color brilliantly, but when using the Microfleur, use several short cycles of 30 seconds or so with a rest of 5 minutes in between. The poppy season is short, so try pressing some for yourself soon!
