Abundance cheques are used in manifestation. Fill out the cheque, fold it towards you 3x and place it in your wallet or purse, on your altar or any sacred space you use.
Write out the cheque with your truest and wildest desires in mind. The cheques are in different colours to amplify the intention behind your manifestation. 
 
Green for financial gain and propserity
Gold for abundance in all aspects of life
Purple for connecting to the abundance in the astral
