A good design
Thick chart paper or wooden board
First trace the design on the paper or board. Apply fevicol to the design part by part and after covering every area that needs the same colour, sprinkle the coloured sand on it. Leave it for a minute and then reverse it on a paper, so that the excess sand falls off. The sand sticks only in that place where fevicol is applied. Continue the same process to fill all the colours.
Use water colours to give outlines and in case any colour sand is appearing dull, you can give it a coat of water colour also to make it bright.
Give it a coat of varnish.
Your sand painting is ready.
