I have yet to come across a vine that didn’t press well! They are so tough after pressing and maintain great color. There was only one problem and that came in the form of small bubbles after using the microwave flower press. Next time I’ll have to try it in my home-made press to see if I can prevent that. I got my home-made press instructions from a fellow WWPFG member. You can view how to make your own and many more great tips on her website: http://www.press-flower.com/drupal/book/export/html/26. Other than the bubbles most of them came out perfect. Happy pressing!
