How to dry flowers: With silica gel
If you want your flowers to look just like they did in your garden, trying using silica gel. The sandy-like substance can be found at craft stores and works best with sturdy flowers like zinnias or roses. Bury your blooms in a large container of silica gel. In a few days to a week, gently uncover vibrant, preserved flowers.
How to dry flowers: By pressing
To use dried flowers for more than household decorating, use the pressed method. Take an encyclopedia or other heavy book. Line a page with parchment or wax paper and arrange flowers face down so they don’t overlap. Close the book and leave untouched for seven to 10 days. Once all the moisture is gone and they have a papery texture, use your pressed flowers to make bookmarks, stationary, or fill a picture frame for pretty wall art.
How to dry flowers: Air drying
Hanging bouquets upside down is the most traditional technique for drying flowers. Gather the flowers in a bunch and secure the stems with a rubber band. Hang upside down in a well-ventilated area out of direct sunlight, like from kitchen rafters or in an empty closet. Watch the petals shrink and change color, and within a few weeks you’ll have beautiful dried flowers in vintage hues. Try arranging them to make this table centerpiece.
