You have asked.
Dried in sand Hollyhocks and Roses.
Place 2 to 3 inches of dry builder's sand
(from the hardware store) into container.
Carefully push fresh flowers into sand.
Keep pouring sand slowly over fresh flowers until they are completely covered.
Be sure to "support" hollyhocks from underneath by carefully pouring sand from the side and again, cover with sand completely.
Place in dry area and cover with light cloth.
After 3 to 4 days pour sand slowly from container.
Flowers will emerge.
This is an old wreath I made from many different flowers which I dried in sand.
I'm always asked why my dried flowers have such bright colors.
Here is the secret: your sand and your flower heads must be very dry.
(leave the sand in the sun for a few hours before placing flowers into it if you think it has taken up moisture)
Pick your flowers in the middle of the day when they have used up most of their moisture.
These were growing in my garden only 3 days ago.
They will be placed on top of a bowl of dried lavender.
You might like to try drying other flowers.
Have fun,
Gina
