Here is one of the cards we did at my recent class.
This card revisits the emboss resist technique and uses the great stamp sets “Extreme Elements” and “Extreme Guitar” (Extreme Guitar is going to retire soon, so if you don’t have it and you want it you know what to do).
The colours I used are Marina Mist and Old Olive.
The card is a very close case of this card here
Happy Stampin’
