Microfleur microwave flower press and supplies
The vast majority of the flowers used in my botanical art are pressed with my 9x9" Microfleur microwave flower press. I've been using it for over 10 years. Flowers press in minutes (as opposed to weeks in a traditional flower press) and they retain their brilliant colors remarkably well.
You can purchase Microfleur products and other helpful flower pressing supplies at my Wooden Deckle Etsy shop.
