At this time of year, we have a lot of beautiful flowers blooming. A cheaper way of drying them is to use a cheap cat litter. Make sure you use the plain clay litter. Line a box with paper towels, put a layer of cat litter on the paper towels. Place your roses (or flowers to be dried) on the litter, making sure they aren't touching. Gently add more of the litter to cover the flowers. They should be dry in about 10 days. Shake them gently to remove excess litter. Spray with the cheap super-hold hair spray. It will seal and protect them. It will take along time to use up all the litter and it works better than the expensive silica gel. The results will be beautiful.
