This week, the D&CO team invites you to create an original collage with a medium board. Demonstration in pictures. 01 - Apply a coat of primer on a medium board. 02 - With painter's tape, separate the two surfaces to be painted. 03 - Paint one side in purple and apply a slate paint on the other side. 04 - Remove the scotch tape and place a ribbon by stapling it to the back of the board. 05 - Slide the drawing clips under the ribbon. 06 - Slide the photos under the drawing pliers. 07 - Finally, write a quick note on the slate to get an original collage.
