Make a smooth henna paste by sifting the dry mehndi henna powder to remove any debris and adding to it a hot mixture of tea or coffee and mustard oil until it has a mud-like firmness.
After the paste is ready take a plastic cone with a very fine key-hole at the end. Pour the paste into the cone and ie the broader end with a rubber band.
Hold the cone in the right hand and gently squeeze the paste on the palm and start making patterns
Keep the palm horizontal and let the patterned-paste rest on it till dry. Warm it near the fire and leave it on for as long as it takes to get the stains deeper. When it is almost dry, dab a piece of cotton in sugar and lemon solution and apply li,ghtly o,n the designs so it ,further darkens to a ,reddish-brown h,ue that can last ,for weeks. After hours wash ,off the hands ,with plain water.
