Pressing dries and preserves flat flowers. While pressing isn't a suitable preserving method for all rose varieties, it works well for drying old-fashioned single-petalled roses such as the butterfly rose cultivars. The method uses weight and pressure to force the moisture from the petals quickly, which preserves most of the colour in the flower. Pressed roses also retain a hint of their fragrance after pressing. Use the roses in paper crafts or in framed flower designs.
Lay a sheet of blotting paper on top of a sheet of cardboard. Alternatively, use unprinted newspaper or non-glossy white typing paper.
Trim the stems from the rose flowers. Arrange the flowers face up on top of the blotting paper, placing them so they don't touch or overlap each other.
Place a second sheet of blotting paper on top of the roses. Lay another piece of cardboard on top of the stack.
Place a heavy phone book or a paving stone on top of the stack. The weight from the book or stone presses the moisture from the roses, while the paper and cardboard absorb the moisture while also protecting the flowers.
Remove the weights after one week and check the roses. The flowers feel dry and papery once properly pressed. If any moisture remains in the petals, replace the weights and press the roses for another two to three days.
Store pressed roses flat in a sealed container or plastic bag. Moisture causes the blossoms to mildew and fall apart.
