Hang the large felt background on a smooth surface or wall using tacks or semi-permanent double stick tape. Double stick foam adhesives are included; however use caution as they may damage the surface.
To help the felt shapes stick to the background, rub the felt between your hands to create a static cling effect.
If you want the felt shapes to be permanently placed, you can use the foam squares included. In addition, you can use double stick tape or fabric glue (not included).
